The present invention relates to a mobile terminal having an intenna, and more particularly, to increase the bandwidth of the intenna while pursuing slimming and compacting of the mobile terminal, thereby improving the overall antenna performance. The present invention relates to a mobile terminal having an intenna.

An antenna provided in a mobile terminal refers to a device for transmitting or receiving electromagnetic waves into a space for transmitting and receiving. The transmitting and receiving antennas have the same basic principle, but may have various shapes depending on the frequency (wavelength) used.

In order to operate the antenna efficiently, it is necessary to resonate at the frequency using the antenna. Vertical antennas provided in mobile terminals, also called coaxial antennas or sleeve antennas, are resonant when the length is 1/4 or 1/2 of the wavelength used, but in practice, the antenna becomes too long. To resonate. Such an antenna has a different radio sensitivity (transmission and reception) depending on the installation direction, length, and the like.

As a result, under the same conditions, the longer the length of the antenna or the larger the volume, the higher the wireless sensitivity.

However, a conventional mobile terminal cannot be equipped with an infinitely long antenna due to the limitation of internal space due to its structure that is changed compactly. Therefore, the radio sensitivity is bound to decrease that much. In particular, in the case of the so-called intenna (intenna) in which the antenna is mounted in the terminal body due to the recent years, the installation space is inevitably restricted.

For example, in the case of the existing mobile terminal, since the volume of the mobile terminal has been relatively large, there is no problem in designing sufficient mounting area and the antenna space in the design of the antenna.

However, at present, since the mobile terminal is designed in a slim and compact structure according to the needs of various users, forming a general trend, there is practically a limit to the installation space of the intenna. Therefore, in some cases, the performance of the antenna which does not meet the needs of the user is applied to the mobile terminal. Of course, in this case, the performance of the mobile terminal is inevitably deteriorated since the performance of the antenna is generally deteriorated.

Accordingly, the present applicant can increase the bandwidth of the antenna while pursuing slimming and compacting (slim & compact) of the mobile terminal in consideration of the current trend, and thus has a mobile terminal having an intenna which can improve the overall antenna performance. Came to suggest.

An object of the present invention is to provide a mobile terminal having an intenna that can increase the bandwidth of the intenna while increasing the bandwidth of the intenna while pursuing slimming and compacting of the mobile terminal.

It is possible to elastically move between standby modes where the area becomes relatively narrow.

The call mode may be formed when the folder part is opened with respect to the body part, and the standby mode may be formed when the folder part is closed with respect to the body part.

FIG. 1 is a perspective view of a folder part in a closed state in a mobile terminal having an antenna according to an embodiment of the present invention, and FIG. 2 is a perspective view of the folder part in an open state in FIG. 1.

As shown in these figures, the mobile terminal 1 according to an embodiment of the present invention has a terminal body 10 and a battery pack 22 coupled to the terminal body 10 to supply power. . The illustrated mobile terminal 1 indicates a so-called foldable cellular phone.

The terminal body 10 is provided between the main body 12, a folder 18 for opening and closing the front of the main body 12, and between the main body 12 and the folder 18, the main body 12 It has the hinge 21 which rotates the folder part 18 with respect to it.

Both sides of the hinge 21 are provided with two-way stereo speakers 23. The bidirectional stereo speaker 23 and a camera not shown are optional. Therefore, the scope of the present invention need not be limited to that shown.

The inner surface of the main body 12 is provided with a plurality of input buttons (13). In the lower part of the input buttons 13, a transmitting unit 14 for transmitting a user's voice to the other party or recording a voice message is formed, and in the upper part thereof, a menu search button 15 is formed.

The side key 16 is provided on the side of the main body 12, that is, the side of the main body 12. The side key 16 is provided to increase the user's convenience with respect to the mobile terminal 1. Unlike the functions of the input button 13 and the menu search button 15 described above, the side key 16 may be used to select additional menus or functions such as manipulating the received volume or key tone.

The inner surface of the folder unit 18 is provided with a large screen internal liquid crystal 19a in which a character or a screen is formed, including a phone number, a state of charge of the battery, a vibration state, an alarm state display, and the like. The internal liquid crystal 19a is adopted as a so-called LCD. The receiver 20 for receiving the voice from the other party is formed on the upper portion of the internal liquid crystal 19a.

The outer liquid crystal 19b is provided on the outer surface of the folder portion 18. The external liquid crystal 19b displays simple information such as text reception status, time, telephone reception status, and the like.

The battery pack 22 is detachably coupled to the rear surface of the main body 12. The battery pack 22 is generally adopted as a rechargeable type, and depending on the type thereof, a lead-acid battery, a nickel cadmium (Ni-Cd) battery, a nickel hydride (Ni-Mh) battery, and a lithium-ion rechargeable battery (Lithium-ion) may be used. ), A lithium polymer rechargeable battery (Polymer) and the like may be applied.

3 and 4 are schematic side views of the mobile terminal corresponding to FIGS. 1 and 2, respectively, illustrating the operation of the antenna module.

As shown in these figures, on the other hand, the main body 30 is provided with a main board 30 in charge of various controls of the mobile terminal. In the case of FIGS. 3 and 4, only the main board 30 is shown in the main body 12 for the convenience of the drawing, but the main board 30 is substantially the main body 30 by various brackets or ribs not shown. It is fixed to the predetermined position within 12.

The upper surface of the main body 12, that is, one side of the upper surface of the main body 12 provided with the input button 13 is provided with an antenna module 40 for transmitting and receiving wireless signals.

In a typical mobile terminal (not shown), a rod-shaped external antenna (not shown) is usually provided, but in the mobile terminal 1 of the present embodiment, a so-called antenna module 40, which is an internal antenna, is provided. do.

The antenna module 40 includes an antenna unit 41 for transmitting and receiving wireless signals, and a unit cover 42 for forming an exterior of the antenna unit 41 so that the antenna unit 41 is partially accommodated.

An exposure hole 12a through which the unit cover 42 is partially exposed is formed at one side of the upper surface of the main body 12 so that the unit cover 42 may be partially exposed from the upper side of the main body 12. However, after the unit cover 42 is fitted into the exposure hole 12a, the unit cover 42 is completely removed from the main body 12 through the exposure hole 12a when the unit cover 42 is elastically operated by the configuration described later. It shall not be dismissed.

Therefore, the inner module 40 is further provided with a means for preventing the detachment of the unit cover 42, which is in charge of the release stop flange portion 42a provided at the rear end of the unit cover 42. The flange for separation release 42a is formed relatively larger than the diameter of the exposed hole 12a.

Meanwhile, the unit cover 42, which is an element of the intena module 40, is exposed from the upper surface of the main body part 12 or partially inserted into the main body part 12 based on the opening / closing operation of the folder part 18. see.

In other words, the antenna module 40 elastically moves between the call mode (see FIG. 4) and the standby mode (see FIG. 3) based on the opening / closing operation of the folder unit 18. Here, the call mode refers to a state in which the antenna module 40 is partially exposed from the upper surface of the main body 12 so that the transmission / reception area of the radio signal is relatively enlarged as shown in FIG. 4.

In addition, the standby mode refers to a state in which the antenna module 40 is partially inserted into the main body 12 to relatively narrow the transmission / reception area of the wireless signal, as shown in FIG. 3. Of course, even in the standby mode, although the wireless signal is transmitted and received through the antenna module 40, it is weak compared to the aforementioned communication mode.

Therefore, the call mode is formed by exposing the antenna module 40 when the folder unit 18 is opened with respect to the body unit 12 as shown in FIG. 4, and the standby mode is shown in FIG. 3. It is formed when the folder portion 18 is closed with respect to the portion 12.

As described above, this structure is one means for preventing the slimming and compacting of the mobile terminal 1. In other words, even if a small antenna module 40 is used, the wireless sensitivity is improved by using a method of securing the volume in order to perform a function as an antenna.

Usually, as shown in FIG. 3 to 4, if the space of the antenna module 40 can be secured by opening the folder 18 to increase the height of the antenna module 40 can be a great help in the implementation of antenna performance. . Substantially, as in the present embodiment, when opening the folder portion 18 to increase the height of the intenna module 40 to secure the space, the antenna volume can be secured more by about 2 cc even if it is increased by about 2 to 3 mm. It is known to be a great help for antenna performance.

On the other hand, the above-described antenna module 40 is electrically connected to the main board 30 by a predetermined connection portion 35. However, in configuring the connection unit 35, as described above, it is preferable that the antenna module 40 moves elastically between the call mode and the standby mode, so that the connection unit 35 may provide a predetermined elastic force to assist this. It is preferable to be manufactured from the material which has.

There may be a variety of such materials, but in the present embodiment, the flexible printed circuit board (FPCB) is connected to the connection part 35 so as to have a predetermined elastic force while electrically connecting the main board 30 and the intena module 40. , Flexible Printed Circuit Board, 35). However, since the scope of the present invention is not limited thereto, the connection part 35 may be made through another material or structure corresponding to the flexible printed circuit board 35 (FPCB).

Looking at the operation of the mobile terminal having such a configuration as follows.

First, as shown in FIG. 3, when the folder part 18 is closed with respect to the main body part 12, the inner surface of the cover part pressurizes the intena module 40 formed on one side of the upper surface of the main body part 12. The module 40 takes a state partially inserted into the main body 12. In this case, the connecting portion 35 made of the flexible printed circuit board 35 (FPCB) is bent by its elasticity.

In the case of FIG. 3, since the intena module 40 is inserted into the main body 12, the volume or space of the intena unit 41 which can be substantially in contact with the external space is relatively reduced. Therefore, the transmission and reception of the radio signal may be relatively weak.

However, as shown in FIG. 4, when the folder portion 18 is opened (opened) with respect to the main body portion 12, the connecting portion 35 made of the flexible printed circuit board 35 (FPCB) is linear by its elasticity. The intena module 40 partially extended into the main body 12 while being extended in shape is partially exposed to the outer side of the upper surface of the main body 12. In this case, a relatively large volume or space that the inner unit 41 can contact with the external space is secured. Therefore, in the case of FIG. 4, the transmission and reception of a radio signal can be relatively strong.

5 and 6 are schematic side views of a mobile terminal having an intenna according to another embodiment of the present invention, showing the operation of the intenna module.

In the above-described embodiment, the inner module 40 may be elastically exposed and inserted with respect to the main body part 12 by the elasticity of the connection part 35 made of the flexible printed circuit board 35 (FPCB). However, the elastic force of the flexible printed circuit board 35 (FPCB) may not be very high.

Thus, in the present embodiment, in order to give a more smooth elastic force to the operation of the antenna module 40, the following structure is further added.

That is, a guide part 51 for guiding the operation of the inner module 40 is made inside the main body part 12, and both ends of the guide part 51 are disposed between the guide part 51 and the unit cover 42. The elastic member 53 is attached so that each may be arrange | positioned. At this time, the elastic member 53 may be employed as a compression spring, the elastic member 53 is a compression spring in the direction in which the inner module 40 is exposed to the outside of the main body 12, that is, the inner module 40 Since it is elastically biased toward the call mode, the elastic operation of the antenna module 40 can be more advantageously performed.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

In the above-described embodiment, the unit cover forming the exterior of the intenna module has been described as being exposed from the main body. However, the unit cover itself may be elastically exposed from the main body without the unit cover.

As described above, according to the present invention, the bandwidth of the antenna can be increased while pursuing slimming and compactness of the mobile terminal, thereby improving the overall antenna performance.
