AI Technical Summary

Problems solved by technology

For example, for the design of the antenna of a wireless communication device, the design verification time is less, resulting in that the resonant frequency is prone to error when the antenna is put into mass production.
The antenna of a wireless communication device generally transmits and receives wireless signals through the radiation part to obtain the required communication frequency band. At this time, the required resonance frequency is generally obtained by increasing the interaction between the circuit components and the radiation part. The short distance from the radiation part will affect the radiation performance of the antenna and increase a lot of production costs

Abstract

The invention provides a radio communication device which comprises a carrier, an antenna and a housing. The antenna is arranged on the carrier; the housing covers the carrier and the antenna; and the antenna comprises a radiation portion. The radio communication device further comprises an adjusting member, wherein the adjusting member is made of conductive materials and can be slidably arranged on the housing and is connected with the radiation portion of the antenna. When the adjusting member slides with respect to the housing, the relative position of the adjusting member and the radiation portion changes, and thus resonance frequency of the antenna is adjusted. According to the radio communication device, the slidable adjusting member is provided, the adjusting member is connected with the radiation portion of the antenna, and the resonance frequency of the antenna inside the radio communication device can be slightly tuned by adjusting the position with respect to the housing, thereby saving cost and enhancing universality and adaptability of the antenna.

Description

technical field [0001] The present invention relates to a wireless communication device. Background technique [0002] With the advancement of wireless communication technology, the upgrading of wireless communication products is accelerating, and the design cycle of wireless communication products is constantly being compressed. For example, for the design of the antenna of a wireless communication device, the design verification time is relatively short, and the resonant frequency is found to be prone to errors after the antenna has been put into mass production. The antenna of a wireless communication device generally transmits and receives wireless signals through the radiation part to obtain the required communication frequency band. At this time, the required resonance frequency is generally obtained by increasing the interaction between the circuit components and the radiation part. The short distance to the radiation part will affect the radiation performance of the...
