Magnetoelectric dipole antenna structure and antenna array

Abstract

The invention provides a magnetoelectric dipole antenna structure and an antenna array, belonging to the technical field of microwave communication. According to the invention, a first antenna assembly and a second antenna assembly which have different polarization modes and are expressed by adopting patch type magnetoelectric dipole antennas are respectively installed on a first dielectric layer and a second dielectric layer, and a radio frequency circuit layer is electrically connected with the first antenna assembly and the second antenna assembly through the first antenna switch and the second antenna switch so as to realize feeding of the first antenna assembly and the second antenna assembly at the same time; and then, the on-off state of the first antenna switch and / or the second antenna switch is regulated and controlled through a digital circuit layer, so the respective operation states of the first antenna assembly and the second antenna assembly are adjusted, the polarization mode switching function of the antenna structure is realized, and multi-polarization of the antenna is conveniently realized; and meanwhile, the mechanical strength of the antenna structure is improved through a multi-layer structure composition mode. Therefore, the multi-polarization difficulty and the processing difficulty of antennas can be reduced, and antenna array realization is facilitated.
