Abstract

The invention discloses a planar and low-profile miniaturized quasi-yagi directional diagram reconfigurable 5G antenna, and relates to the technical field of miniaturized 5G antennas and sub 6GHz application. A novel reconfigurable quasi-yagi structure is adopted, specifically, a dipole antenna serves as an excitation source antenna, the reflection effect on an excitation source is achieved through a capacitive loading reflector, and directional radiation is formed; meanwhile, capacitive loading is formed, and miniaturization design is achieved; switching of forward orientation, omnidirectional orientation and backward orientation asymmetric radiation patterns can be realized by controlling the state of the diode. And an artificial phase shift surface is placed on the basis, and three-beamdirectional scanning is carried out, so that the low-profile directional diagram reconfigurable antenna is realized, and the performance requirements of different application scenes can be met. The antenna has the advantages of small size, wide working bandwidth, high antenna radiation efficiency, wide antenna beam coverage, suitability for indoor wide-angle domain communication, easiness in production and application, flexible and quick response of an electric control scheme, high stability and the like.

Description
