Embodiment Construction

[0012] figure 2 and image 3 Shown is a dual-band antenna 100 of a preferred embodiment of the present invention, which can be applied to wireless communication devices such as mobile phones and PDAs. In this embodiment, one is applied to mobile phone 200 (please refer to Figure 4 ) of the dual-band antenna 100 as an example for illustration. The dual-band antenna 100 is disposed on a base body 50 inside the mobile phone 200 . The base body 50 can be a part of a printed circuit board (PCB) of the mobile phone 200 .

[0013] The base body 50 is roughly a cuboid, which includes an end surface 52 , a top surface 54 and a side surface 56 , and the two end surfaces 52 , the top surface 54 and the side surfaces 56 are perpendicular to each other. A grounding point (not shown) and a signal feed-in point (not shown) manufactured according to the prior art may be provided on the side 56 , the grounding point is electrically connected to the base 50 and provides grounding for the ...

Abstract

The invention provides a dual band antenna, which comprises a first radiating body, a second radiating body, a feed in end and a grounding end, and is in an inversed F shape, wherein all of the first radiating body, the second radiating body, the feed in end and the grounding end have a flat sheet structure; the first radiating body and the second radiating body are connected and in the same plane; and the feed in end and the grounding end are positioned in another plane and are both connected with the first radiating body vertically. The invention also provides a wireless communication device using the same. The dual band antenna requires a small installation space and low design and development cost.

Description

technical field [0001] The invention relates to an antenna, in particular to a dual-frequency antenna and a wireless communication device using the dual-frequency antenna. Background technique [0002] In mobile phones, personal digital assistants (Personal Digital Assistant, PDA) and other wireless communication devices, the antenna, as a component used to transmit and receive radio waves to transmit and exchange radio signals, is undoubtedly one of the most important components in wireless communication devices one. At present, wireless communication devices generally need to have the function of communicating in dual-frequency or more frequency bands, so their antenna devices generally use dual-frequency or multi-frequency antennas. [0003] see figure 1 , an existing dual-band antenna 80 includes a first radiating arm 82 and a second radiating arm 84, the first radiating arm 82 and the second radiating arm 84 are elongated structures and are used for sending and receiv...
