Magnetoelectric Dipole Antenna Structure and Antenna Array

Abstract

The application provides a magnetoelectric dipole antenna structure and an antenna array, which relate to the technical field of microwave communication. In this application, by installing the first antenna component and the second antenna component with different polarization modes on the first dielectric layer and the second dielectric layer and using a patch type magnetoelectric dipole antenna, the radio frequency circuit layer passes through the second antenna component. An antenna switch and a second antenna switch are electrically connected to the first antenna component and the second antenna component respectively, so as to simultaneously feed power to the first and second antenna components. Then, the on-off state of the first antenna switch and / or the second antenna switch is regulated through the digital circuit layer to adjust the respective operating states of the first and second antenna components, and realize the polarization mode switching function of the antenna structure, which is convenient Realize antenna multi-polarization. At the same time, the mechanical strength of the antenna structure is improved through the composition of the multi-layer structure. Thus, the present application can reduce the difficulty of antenna multi-polarization and antenna processing, so as to facilitate the realization of antenna array.
