Description

Electronic device capable of enhancing antenna signal strength and operation method thereof

The present invention relates to an electronic device capable of enhancing antenna signal strength and an operation method thereof, and more particularly to an electronic device for enhancing antenna signal strength by using a metal foil and an operation method thereof.

As mobile communication devices become more and more popular, their role in emergency rescue is becoming more and more important. For example, the 3rd Generation Partnership Project (3GPP), the European Telecommunications Standards Institute (ETSI), etc., stipulate that dialing 112 is an emergency call. As long as the mobile communication device can receive the signal, even if it is not the base station signal of the operator rented by the user, 112 can be connected via it. However, when the rescuer is in an environment where the mobile communication device does not receive the base station signal (for example, the mountain), it cannot be rescued through the mobile communication device.

One of the objects of the present invention is to provide an electronic device capable of enhancing antenna signal strength and an operation method thereof to solve the above problems.

According to an embodiment, an electronic device capable of enhancing antenna signal strength of the present invention includes a housing, an antenna, and a metal foil. The antenna is disposed on the housing. The metal foil is detachably disposed on the casing, and the metal foil is marked with four fixed marks. When the metal foil is detached from the casing, the four ends of the two fixing members can be respectively fixed at the four fixed marks, so that the metal foil forms a curved surface. The housing is movable relative to the curved surface such that the antenna is at a predetermined distance from one of the vertices of the curved surface to enhance the signal strength of the antenna through the curved surface.

According to another embodiment, the method for enhancing the antenna signal strength of the present invention is applicable to an electronic device, wherein the electronic device includes a casing, an antenna, and a metal foil. The antenna is disposed on the casing, and the metal foil is detachably It is placed on the housing and four fixed marks are marked on the foil. The operation method for enhancing the strength of the antenna signal comprises: removing the metal foil from the casing; fixing the four end portions of the two fixing members to the four fixed marks respectively, so that the metal foil forms a curved surface; and moving the casing relative to the curved surface, The antenna is spaced a predetermined distance from one of the vertices of the curved surface to enhance the signal strength of the antenna through the curved surface.

In summary, when the user is in an environment where the electronic device does not receive the base station signal completely (for example, a mountain), the metal foil can be detached from the housing and the metal foil is curved by the two fixing members. Then, the housing is moved relative to the curved surface formed by the metal foil to concentrate the electromagnetic waves in a specific direction through the curved surface (that is, to enhance the directivity of the antenna). Thereby, the user can enhance the signal strength of the antenna through the curved surface formed by the metal foil, thereby increasing the chance that the antenna of the electronic device receives the signal of the nearby base station. Since the metal foil is detachably disposed on the casing of the electronic device when not in use, it is possible to avoid the embarrassing situation that is forgotten to be carried and cannot be used in an emergency, without requiring additional storage.

Please refer to FIG. 1 to FIG. 3 . FIG. 1 is a schematic diagram of an electronic device 1 capable of enhancing the antenna signal strength according to an embodiment of the present invention. FIG. 2 is the metal foil 14 of FIG. 1 from the housing 10 . A schematic view of the curved surface 140 is formed by disassembling and spreading, and the second fixing member 16a, 16b is formed. FIG. 3 is a schematic diagram showing the antenna 12 in FIG. 1 at a predetermined distance D from the apex 142 of the curved surface 140 in FIG.

As shown in FIG. 1 , the electronic device 1 capable of enhancing the strength of the antenna signal comprises a housing 10 , an antenna 12 and a metal foil 14 , wherein the antenna 12 is disposed on the housing 10 , and the metal foil 14 is detachably disposed on the housing On the housing 10. In practical applications, the electronic device 1 can be any electronic device with communication functions, such as a mobile phone, a personal digital assistant, a tablet computer, etc. The antenna 12 can be a monopole anterna or a dipole antenna. Patched Inverse F Antenna (PIFA) or other form of antenna. In this embodiment, the metal foil 14 may be a copper foil, a tin foil or other metal foil having high electrical conductivity, and is disposed on the casing 10 in a crimped form. For example, the foil 14 may be disposed in a curled manner in a space or other space of the housing 10 for accommodating the stylus. In another embodiment, the foil 14 can also be folded over the housing 10. For example, the foil 14 can be folded over the back cover, battery cover or other portion of the housing 10. In other words, the foil 14 can be folded or crimped onto the housing 10, depending on the application. Generally, the electronic device 1 is also provided with soft and hard components necessary for operation, such as a central processing unit, a memory, a power supply, an operating system, an application program, a communication module, etc., depending on the actual application.

When the user is in an environment where the antenna 12 of the electronic device 1 is completely unable to receive the base station signal (for example, a mountain), the metal foil 14 can be detached from the casing 10 and spread out. The curved surface 140 is formed by fixing the metal foil 14 by the two fixing members 16a, 16b, as shown in Fig. 2. Next, the user moves the housing 10 against the curved surface 140 formed by the metal foil 14 such that the antenna 12 is at a predetermined distance D from one of the vertices 142 of the curved surface 140 to concentrate the electromagnetic waves in a specific direction through the curved surface 140 (ie, Enhancing the directivity of the antenna 12). Thereby, the user can enhance the signal strength of the antenna 12 through the curved surface 140 formed by the metal foil 14, thereby increasing the chance that the antenna 12 of the electronic device 1 receives the signal of the nearby base station.

In this embodiment, the metal foil 14 is marked with four fixed marks 144a, 144b, a predetermined length L, and an operation indication 146. In this embodiment, the fixed marks 144a, 144b may be fixed holes. The operation indication 146 is used to explain the operation of the housing 10, the antenna 12, the foil 14 and the two fixing members 16a, 16b. In other words, after the metal foil 14 is detached from the casing 10 and spread out, the user can complete the above operation step by step according to the instruction of the operation instruction 146, thereby preventing the user from being mistaken for failing to operate correctly in a critical situation. Help for help.

In this embodiment, the user needs to fix the metal foil 14 with two fixing members 16a, 16b of a specific length to form a curved surface 140 that can effectively concentrate electromagnetic waves. Preferably, the curved surface 140 can be a paraboloid, and one of the focal points of the paraboloid is spaced apart from the vertex 142 by a predetermined distance D, that is, the antenna 12 is disposed at a focal point toward the paraboloid. Since the length of the fixing members 16a, 16b is selected in accordance with the size of the metal foil 14, the predetermined length L indicated on the metal foil 14 is the length for the user to compare the required fixing members 16a, 16b.

Therefore, when the user detaches the metal foil 14 from the casing 10 and spreads out, the two fixing members 16a, 16b having the corresponding length can be obtained from an environment (for example, the environment where the user is located) according to the predetermined length L. (for example, branches, chopsticks, pens, etc.), then, the four ends of the two fixing members 16a, 16b are respectively fixed to the four fixed marks 144a, 144b, so that the metal foil 14 forms the curved surface 140. For example, the two ends of the two fixing members 16a can be respectively fixed at the two opposite fixed marks 144a, and the two end portions of the two fixing members 16b are respectively fixed at the opposite two fixed marks 144b. . Therefore, when the two fixing members 16a, 16b When the four end portions are respectively fixed to the four fixed marks 144a and 144b, the two fixing members 16a and 16b cross each other. Then, the user moves the housing 10 relative to the curved surface 140 formed by the metal foil 14 so that the antenna 12 is at a predetermined distance D from the apex 142 of the curved surface 140, so that the signal intensity of the antenna 12 can be enhanced by the curved surface 140. It should be noted that, by proper design, the intersection point P of the two fixing members 16a, 16b and the apex 142 of the curved surface 140 are separated by a predetermined distance D, so that the user only needs to position the antenna 12 at the intersection of the two fixing members 16a, 16b. At P, a position can be quickly found which can effectively enhance the signal strength of the antenna 12 through the curved surface 140.

It should be noted that the present invention can also detachably mount the two fixing members 16a, 16b on the casing 10 to prevent the user from finding a suitable fixing member in an emergency. When the two fixing members 16a, 16b are detachably disposed on the housing 10, the user can directly detach the metal foil 14 and the two fixing members 16a, 16b from the housing in an emergency and according to the operation instruction 146 Do the above.

After the user moves the housing 10 against the curved surface 140 formed by the metal foil 14 so that the antenna 12 is at a predetermined distance D from the apex 142 of the curved surface 140, if the antenna 12 still does not receive the base station signal, the user can hold the metal foil. 14 is rotated at an appropriate angle with the housing 10 to search for nearby base station signals. When the user performs the operation, the housing 10 should be paralleled to the line connecting the vertex 142 and the intersection point P in FIG. 3 as much as possible, and the hand or other parts of the body should be prevented from blocking the curved surface 140 as much as possible to avoid affecting the transmission and reception of the signal.

Referring to FIG. 4 and FIG. 5, FIG. 4 is a schematic view of a parabola 3, and FIG. 5 is a front view of the foil 14 formed by the two fixing members 16a, 16b. As shown in Fig. 4, the distance from the vertex O of the parabola 3 to the focal point F is C, and the positive focal length of the parabola 3 is 4C. The equation for parabola 3 is 4CY=X ² , so the coordinates of focus F can be expressed as (0, C). Assuming C = 1, 4Y = X ² , and the coordinates of the focus F can be expressed as (0, 1). Since the Y coordinate of the focus C is 1, the integral of the positive focal length can be integrated (from X = -2 to +2, that is, from (-2, 1) to (2, 1)), and the integral result is 4.5912. In this embodiment, the size of the above-mentioned metal foil 14 can be set to 21 cm * 30 cm (corresponding to the size of A4 paper). When the unit is 6 cm into the above calculation method, the distance C from the vertex 0 to the focus F is 6 cm, that is, the predetermined distance D described above can be set to 6 cm. The positive focal chord arc length is the distance between the two fixed marks 144a, 144b of the metal foil 14 (4.5912 * 6 = 27.5 cm), so that the long side dimension of the metal foil 14 is set to 30 cm is appropriate, and the fixed mark 144a, The distance between 144b and the side of the foil 14 is set to 1.25 cm ((30-27.5)/2=1.25), respectively. As shown in FIGS. 4 and 5, when the fixed marks 144a and 144b after the curved surface 140 are formed, the longer distance d1 in the space is set to 4C=24 cm, and the fixed marks 144a and 144b after the curved surface 140 are formed. When the shorter distance d2 in the space is set to 21-(1.25*2) = 18.5 cm, the length of the fixing members 16a, 16b can be set to = 30.3 cm. In other words, the present invention can push back the length of the desired fasteners 16a, 16b from the desired curved surface 140.

Please refer to FIG. 6. FIG. 6 is a flowchart of an operation method for enhancing antenna signal strength according to an embodiment of the present invention. The method of operation in FIG. 6 is for operating the electronic device 1 described above to utilize the foil 14 to enhance the signal strength of the antenna 12. First, step S100 is performed to remove the foil 14 from the casing 10. Next, in step S102, the four end portions of the two fixing members 16a, 16b are respectively fixed to the four fixed marks 144a, 144b, so that the metal foil 14 forms the curved surface 140. Finally, step S104 is performed to move the housing 10 relative to the curved surface 140 such that the antenna 12 is at a predetermined distance D from the apex 142 of the curved surface 140 to enhance the signal strength of the antenna 12 through the curved surface 140. It should be noted that the detailed operation manner is as described above, and details are not described herein again.

In summary, when the user is in an environment where the electronic device does not receive the base station signal completely (for example, a mountain), the metal foil can be detached from the housing and the metal foil is curved by the two fixing members. Then, the housing is moved relative to the curved surface formed by the metal foil to concentrate the electromagnetic waves in a specific direction through the curved surface (that is, to enhance the directivity of the antenna). Thereby, the user can enhance the signal strength of the antenna through the curved surface formed by the metal foil, thereby increasing the chance that the antenna of the electronic device receives the signal of the nearby base station. Since the metal foil is detachably disposed on the casing of the electronic device when not in use, no additional storage is required, It can avoid the dilemma of forgetting to carry and being unable to use in an emergency.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
