Problems solved by technology

However, when the antenna needs to change its installation position, or needs to apply the antenna to other wireless communication devices, the resonant frequency of the antenna will inevitably shift due to changes in the environment around the antenna, which will affect the transmission and reception performance of the signal

Abstract

The present invention provides a wireless communication device, which includes a carrier, an antenna, a housing and an adjustment member. The antenna is arranged on the carrier. The housing covers the carrier and the antenna. The antenna includes a first radiation part and a The second radiating part is arranged at intervals. The adjusting part is made of conductive material, which is slidably arranged on the casing and connected between the first radiating part and the second radiating part. When the adjusting part slides relative to the casing , the relative positions of the adjusting member and the first radiating part and the second radiating part are changed to adjust the resonant frequency of the antenna. The wireless communication device can fine-tune the resonant frequency of the antenna, thereby enhancing the versatility of the antenna.

Description

technical field [0001] The present invention relates to a wireless communication device, in particular to a wireless communication device capable of finely adjusting the frequency of sending and receiving of an antenna. Background technique [0002] In order to shorten the antenna design cycle of wireless communication devices such as mobile phones, most antennas are currently designed for specific wireless communication devices, that is, the size and spatial placement of the antenna only consider the installation environment inside the corresponding wireless communication device. However, when the installation position of the antenna needs to be changed, or the antenna needs to be applied to other wireless communication devices, the environment around the antenna changes, which will inevitably lead to a shift in its resonant frequency, which will affect the performance of transmitting and receiving signals. Contents of the invention [0003] In view of this, it is necessa...
