Problems solved by technology

In the case of using the shell as the grounding plate of the antenna radiation unit, adding a short-circuit pin to the shell will affect the current distribution on it, which may change the working frequency band and radiation performance of the original antenna, making it difficult to achieve excellent radiation performance level, will eventually affect the communication quality of the system
[0004] Especially for the case of multi-port shared radiating unit, since the short circuit has different effects on the surface

Abstract

The invention relates to an antenna assembly used for a mobile terminal and the mobile terminal using the antenna assembly. According to the antenna assembly, an electric conduction outer shell as a part of the antenna assembly serves as a radiating element of an antenna. The antenna assembly can work in a plurality of communication frequency bands. At least one short-circuit pin is arranged between the radiating element and an earth plate of a printed circuit board. Through the position design of the short-circuit pin, the antenna can be in ground connection to achieve electrostatic discharge, and meanwhile the original radiating performance is not changed. Moreover, even if multiple antenna ports are arranged, good isolation among all the antenna ports can be kept.

Description

technical field [0001] The present invention relates to an antenna technology, in particular to an antenna assembly for a mobile terminal and a mobile terminal using such an antenna assembly. Background technique [0002] In the technical solution of using the conductive shell of the mobile terminal as the antenna radiation unit, the metal shell of the mobile terminal and the grounding plate of the internal printed circuit board form a structure similar to a microstrip patch antenna, which is different from that used in mobile terminals. traditional antenna form. The antenna disclosed by this technical solution can be attributed to the microstrip antenna in theory. The microstrip antenna has the advantages of high radiation performance, easy conformality, flexible antenna form, and easy realization of circular polarization, dual polarization, and multi-frequency operation. However, the size of the microstrip antenna is large, and the large suspended metal as the radiation ...
