Abstract

The invention provides an adjustable antenna for all-metal structural communication terminal equipment. A slit is formed in a rear metal shell, and an adjustable electric device is connected between two sides of the slit; due to the slit, when the antenna is applied to the all-metal structural communication terminal equipment, an electromagnetic wave signal can be effectively radiated or received. A bracket is arranged on the antenna; when a metal sheet covering or just not covering the slit is arranged on the bracket, the signal can be fed out through the slit in a metal sheet coupling feed manner so as to execute an antenna function; by arrangement of the adjustable electric device, the working frequency band of the antenna can be adjusted, so that the bandwidth of the antenna is effectively expanded. The antenna is simple in structure and is variable; the working frequency band is easy to adjust, so that the adjustable antenna is very suitable for the all-metal structural communication terminal equipment.

Description

technical field [0001] The invention relates to an antenna, in particular to an adjustable antenna for communication terminal equipment with an all-metal structure. Background technique [0002] With the rapid development of wireless communication, its requirements on the rate and quality of data transmission are getting higher and higher. Currently, there are various technologies and standards for wireless communication. The development process of wireless communication from 2G to 3G and then to 3.9G is the process from mobile voice service to high-speed data service. Among them, LTE (Long Term Evolution, Long Term Evolution), as the main next-generation technology in the wireless network field, can provide faster transmission rate and higher transmission quality. In order to provide richer wireless communication functions, current mobile communication terminal devices such as notebook computers, tablet computers, and mobile phones need antennas that can meet various wire...
