Embodiment Construction

[0015] see figure 1 and figure 2 , a preferred embodiment of the present invention provides an antenna structure 100, which is applied in wireless communication devices such as mobile phones.

[0016] The antenna structure 100 includes a circuit board 10 , an antenna 20 , a connector 30 , a cover 40 , a slide 50 and a radiation portion 60 .

[0017] A notch 12 is defined on the circuit board 10 , and a side edge 14 is formed at the notch 12 . A feed-in point (not shown) and a ground point (not shown) are set on the side 14, the feed-in point is used for feeding electrical signals to the antenna structure 100, and the ground point is used to provide the antenna structure 100 with Grounding, through the feeding point and the grounding point, the antenna structure 100 forms a current loop.

[0018] In this embodiment, the antenna 20 is disposed in the notch 12 of the circuit board 10 to save space. The antenna 20 includes a feeding end 22 , a grounding end 24 and a radiator ...

Abstract

The invention provides an antenna structure and a wireless communication device with the same. The antenna structure comprises an antenna, a connector, a cover plate, a sliding plate and a radiation part, wherein the connector is connected with the antenna and extends towards the direction of the cover plate, the sliding plate is slideably arranged on the cover plate, the cover plate is provided with an opening, the radiation part is fixed on the sliding plate and is exposed from the opening, and the sliding plate can be slid to make the radiation part and the connector be in contact or separated so as to enable the antenna structure to receive different wireless signals. The antenna structure occupies a smaller space of the wireless communication device and is conducive to the development of a light and thin wireless communication device.

Description

technical field [0001] The invention relates to an antenna structure, in particular to an antenna structure with switchable operating frequency and a wireless communication device with the antenna structure. Background technique [0002] Most of the current wireless communication devices such as mobile phones have multiple working frequency bands, correspondingly equipped with various antennas, such as conventional GSM / CDMA wireless communication antennas, Bluetooth (Bluetooth, BT) antennas, wireless fidelity (wirelessfidelity, WIFI) antennas And Global Positioning System (Global Position System, GPS) antenna, etc. Since the frequency bands used by different antennas are quite different, currently most multi-frequency wireless communication devices must separately set up an antenna for each working frequency band to send and receive signals of the frequency band. This will increase the production cost of the antenna device, and also increase the volume of the antenna device...
