The radiator 210b is configured to transmit and receive a multi-band wireless signal. That is, the radiator 210b may function as a multiband antenna.

As illustrated, the first slot 220 may be formed long along one direction. Through this, the ground portion 210a and the radiating portion 210b are respectively disposed on both sides based on the first slot 220, and the larger area becomes the ground portion 210a and the narrower radiation portion 210b. Can be Since the first slot 220 is formed long in one direction, the radiating portion 210b is also made long in one direction along the first slot 220.

In this case, the width and length of the first slot 220 may be adjusted according to resonance characteristics. In addition, the first slot 220 may be formed at one end of the circuit board 181 so that one end functions as the antenna device 200.

The ground portion 210a may be a portion connected to the radiating portion 210b and ground. In this case, the current flowing through the ground connection can return to the ground portion 210a.

The ground part 260 may be a part electrically connected to the ground part 210a at the end of the radiation part 210b.

The antenna device 200 can be driven as a PIFA antenna by the above conductive path. The antenna device 200 of this example is provided with a broadband feeding structure to impart multiband and broadband characteristics to the structure of the PIFA antenna. Hereinafter, the broadband feeding structure will be described in more detail.

The broadband feeding structure includes a first capacitor element (C _L , 270) and a second capacitor element (C _H , 280 ).

The element 270 is disposed. Through this, a power feeding structure or an antenna structure exhibiting broadband characteristics in fundamental mode is implemented.

In addition, according to the drawing, the second capacitor element 280 is disposed on the opposite side of the first capacitor element 270 with the power feeding portion 240 interposed therebetween. The second capacitor element 280 is disposed in a direction parallel to the first capacitor element 270 and the power supply unit 240 to electrically connect the ground portion 210a and the radiating portion 210b.

More specifically, another part of the first pattern portion 210b' protrudes in the first slot 220 toward the ground portion 210a, and a second capacitor element between the protruding portion and the ground portion 210a 280 is placed. Through this, a power feeding structure or an antenna structure exhibiting broadband characteristics in a high-order mode can be implemented.

In this example, an adjustment mechanism capable of adjusting electromagnetic coupling between the antenna having the slot structure and the broadband power supply structure is disclosed. Hereinafter, this adjustment mechanism will be described in more detail.

According to the illustration, the adjustment mechanism can be implemented by the second slot 230 and the concentrated water purifying element 250.

For example, a second slot 230 is formed in the radiating portion 210b to divide the radiating portion 210b into a first pattern portion 210b' and a second pattern portion 210b". 230 is formed long along at least one direction In addition, the second slot 230 is connected to the first slot 220, through which the first pattern portion 210b' and the second pattern portion ( 210b").

The second slot 230 extends along one side of the first slot 220 to a point of one side of the first slot 220. That is, one end of the second slot 230 communicates with a point of the first slot 220. Accordingly, the first pattern portion 210b' and the second pattern portion 210b" may be physically separated from each other by one end of the second slot 230 connected to the one point.

The second slot 230 may have a bent shape at least at one point. The bent shape is located at a portion adjacent to the other end of the second slot 230. That is, the portion adjacent to the other end is formed to face a side perpendicular to one side of the first slot 220. The ground portion 260 may be implemented by the bent shape.

By the formation of the second slot 230, the first pattern portion 210b' becomes a part disposed between the first slot 220 and the second slot 230. More specifically, the first pattern portion 210b' faces the ground portion 210a with the first slot 220 therebetween, and the second pattern portion 210b" with the second slot 230 therebetween. The second pattern portion 210b" is disposed to face the first pattern portion 210b' with the second slot 230 interposed therebetween, and along the first slot 220. It can be a long formed part.

According to the drawing, the first pattern part 210b' is connected to the power supply through the power supply part 240, and a concentrated water purifying element is provided in a separated part of the first pattern part 210b' and the second pattern part 210b". 250) are arranged to connect the separated portions.

The concentrated integer element 250 is formed to control the coupling between the first pattern portion 210b' and the second pattern portion 210b". The first pattern portion 210b' and the second pattern portion 210b" As the centralized water purification element 250 is disposed in the separated portion of the current, the current flowing through the power supply unit 240 can be controlled, and the bandwidth of the radiation unit 210b can be improved.

The concentrated integer element 250 may be formed of an inductor, a capacitor, or a combination of an inductor and a capacitor (filter) connecting the first pattern portion 210b' and the second pattern portion 210b". The pattern portion 210b' is grounded by the ground portion 260 at the opposite side of one end of the first pattern portion 210b' (the other end of the first pattern portion 210b') connected to the concentrated integer element 250. It is connected to (210a) and the ground.

The current supplied from the power supply unit 240 to the first pattern unit 210b' flows through the centralized integer element 250 to the second pattern unit 210b", and the ground unit 210a is grounded by the ground unit 260. Electromagnetic waves are emitted from the second pattern portion 210b" by the flow of the current.

According to the structure described above, the ground portion 210a and the radiating portion 210b are divided by the first slot 220, and the power feeding portion 240 and the ground portion 260 are connected to the radiating portion 210b. A second slot 230 is added to the antenna of the structure, and the part where the electrical connection of the radiating part 210b is cut off by the second slot 230 (the first slot 220 and the second slot 230 are connected) A new antenna device 200 to which the centralized integer element 250 is connected is implemented.

The performance of the new antenna device 200 can be confirmed by FIGS. 6A to 6D. 6A and 6B are graphs showing radiation characteristics and input impedance when there is no adjustment mechanism, and FIGS. 6C and 6D show radiation characteristics and input impedance when the adjustment mechanism is provided. It is a graph.

Referring to FIGS. 6A and 6B, it is shown on the smith chart that the locus size of each mode is large, so that a bandwidth of -6 dB or less is difficult to obtain. On the other hand, in FIGS. 6C and 6D, it is confirmed that the size of the locus of the fundamental mode and the high-order mode is controlled, and it can be seen that a broadband characteristic operating in a desired band is implemented.

With the new antenna device 200, the electromagnetic coupling between the antenna having a slot structure and the broadband feeding structure is large, and thus a problem of the antenna device having the slot structure that does not obtain broadband characteristics can be solved.
