Abstract

The invention discloses a variable polarization antenna and a variable polarization antenna array. The variable polarization antenna particularly comprises a first antenna structure, a first variablepolarization control structure, a second antenna structure, a second variable polarization control structure and a combining structure, wherein the first antenna structure is connected with the firstvariable polarization control structure; the second antenna structure is connected with the second variable polarization control structure; the first variable polarization control structure and the second variable polarization control structure are connected with the combining structure; and electric fields of the first antenna structure and the second antenna structure are vertical. According tothe variable polarization antenna of the invention, through controlling the phase and the amplitude of the electric field of the antenna, random polarization of the antenna can be realized.

Description

technical field [0001] The invention relates to the technical field of antenna communication, in particular to a variable polarization antenna and a variable polarization antenna array. Background technique [0002] Polarization is an important indicator of antennas, and it is also a resource that is seldom used in electronic warfare antennas. Polarization has an important impact on the performance of the system. How to develop and utilize the antenna polarization characteristics, especially the technology of variable polarization is one of the new technologies developed by radar and electronic warfare. [0003] The polarization of most radars is linear polarization, there are also circular polarization radars, in recent years there has been increasing interest in variable polarization in radar systems for the purpose of identifying and classifying targets and jamming signals within the main beam big. There are two main purposes of changing the polarization of the radar: o...
