Problems solved by technology

However, since the impedance matching circuits are generally installed on the circuit board inside the wireless communication device, this existing method often needs to disassemble and assemble components on the internal circuit board of the wireless communication device, which may still cost a lot of money and has the risk of damaging the circuit board. and the risk of affecting the performance of the wireless communication device itself

Abstract

The invention provides an antenna assembly which comprises an antenna, a substrate and a plurality of filling blocks, wherein a plurality of grooves are arranged on the substrate; the antenna is attached to the substrate and covers all or part of the grooves; the dielectric coefficient of the filling blocks is greater than the dielectric coefficient of the substrate; and the filling blocks are selectively arranged in all or part of the grooves to increase the dielectric coefficient of the groove area so that the work frequency of the antenna which covers above the grooves provided with the filling blocks is correspondingly adjusted. Through the antenna assembly, the frequency can be effectively adjusted. The invention also provides a wireless communication device using the antenna assembly.

Description

technical field [0001] The invention relates to an antenna assembly, in particular to an antenna assembly with adjustable working frequency and a wireless communication device using the antenna assembly. Background technique [0002] Wireless communication devices are widely used in daily life, and antennas are an essential component of wireless communication devices. In order to avoid consuming more time and cost for redesigning the antenna during production, the same antenna may often be used in multiple wireless communication devices. At this time, it is generally necessary to adjust the working frequency of the antenna according to the working requirements of different types of wireless communication devices, so as to ensure better communication effects when the antenna is installed in various types of wireless communication devices. [0003] At present, most of the existing methods adjust the working frequency of the antenna by changing the impedance matching circuit s...
