A wireless communication apparatus according to an embodiment of the present invention includes a plurality of band-forming parts inserted between a plurality of mutually spaced antenna parts and the plurality of mutually spaced antenna parts to electrically connect the mutually spaced parts of the antenna parts. An antenna; A power supply unit having one side connected to the main board and the other side connected to any one of the plurality of mutually spaced antenna units and electrically connected to the multi-band forming unit; And at least one ground part connected to the main board at one side and connected to at least one antenna part not connected to the power supply part, and electrically connected to the multi-band forming part.
Description
Embodiments of the present invention relate to a wireless communication device, and more particularly, to a wireless communication device including an antenna for transmitting and receiving a multi-band signal.
Recently, a wireless terminal equipped with a function of receiving a TV broadcast signal (including terrestrial DMB broadcasting) while a multimedia transmission and reception function is added to a wireless terminal in addition to functions such as voice communication or text message has been developed and spread. In general, the TV frequency band is divided into a VHF (174 ~ 216 MHz) band and a UHF (470 ~ 870 MHz) band. In Korea, the VHF band is used as the TV frequency band, while the US and Japan use both the VHF band and the UHF band as the TV frequency band. Therefore, in order to receive a TV broadcast signal regardless of a country (or region), the wireless terminal must be able to receive both the VHF band and the UHF band.
As shown in FIG. 1, the conventional
Prior art 2
The conventional wireless terminal receives two VHF bands and one UHF band by placing two matching terminals having different paths on one load antenna on a main board. In this case, since two matching ends having different paths must be formed on the main board, there is a disadvantage in that the volume of the matching circuit in the main board becomes large.
Prior Art 3
In the conventional wireless terminal, a method of forming a double resonance by inserting a helical structure into one rod antenna is used. However, this method can form a double resonance in the VHF band and the UHF band, but in the case of the UHF band, resonance occurs only in some frequency bands and cannot satisfy the full frequency bandwidth of the UHF band reaching about 400 MHz. There is this.
An embodiment of the present invention is to provide a wireless communication device that can receive both the VHF band and UFH band with one antenna, in particular the full frequency band of the UHF band up to 400 MHz.
A wireless communication apparatus according to an embodiment of the present invention includes a plurality of band-forming parts inserted between a plurality of mutually spaced antenna parts and the plurality of mutually spaced antenna parts to electrically connect the mutually spaced parts of the antenna parts. An antenna; A power supply unit having one side connected to the main board and the other side connected to any one of the plurality of mutually spaced antenna units and electrically connected to the multi-band forming unit; And at least one ground part connected to the main board at one side and connected to at least one antenna part not connected to the power supply part, and electrically connected to the multi-band forming part.
At least one of the grounding portion and the power feeding portion is formed such that the other side is connected to surround a portion of an outer circumferential surface of the antenna portion.
The ground portion and the power feeding portion are integrally formed in a modular form mounted on the main board.
According to the exemplary embodiment of the present invention, the matching circuit inserted into the antenna unit may be electrically connected to the power supply unit and the ground unit, respectively, to form resonances in the VHF band and the UHF band, and to implement a wide band in the UHF band. It becomes possible. In addition, by inserting the multi-band forming unit into the antenna to be integrally formed with the antenna, it is not necessary to implement a separate matching circuit on the main board in the wireless terminal. In this case, since the area for the matching circuit is not required on the main board in the wireless terminal, the space efficiency can be increased and the volume of the wireless terminal can be reduced.
