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.

Description

technical field [0001] The present application relates to the technical field of microwave communication, in particular, to a magnetoelectric dipole antenna structure and an antenna array. Background technique [0002] With the continuous development of science and technology, microwave communication technology is more and more widely used in various industries, and people have put forward higher requirements for the signal transmission and reception performance of the antenna. Among them, the magnetoelectric dipole antenna has a wide operating frequency band and a wide axial ratio. Beamwidth, stable in-band gain flatness, stable unidirectional radiation pattern, and low cross-polarization have gained widespread attention in the field of microwave communications. For the magnetoelectric dipole antenna, the conventional magnetoelectric dipole antenna still has the problem that it is difficult to achieve multi-polarization, and the overall use of a three-dimensional structure ...
