Abstract

The invention belongs to the technical field of high-power microwave transmitting antennas, and provides a high-power microwave phased-array antenna with reconfigurable leftward and rightward rotation circular polarization, wherein the high-power microwave transmitting antenna also has two-dimensional phase scanning and polarization reconfiguration functions. According to the high-power microwave phased-array antenna, reconfiguration leftward and rightward rotation circular polarization patch antenna units form an array, so angular phase rotation of array elements and polarization configuration can be achieved by means of one motor, and the array has the beam two-dimensional phase scanning function and the on-line real-time polarization reconfiguration function simultaneously. The high-power microwave phased-array antenna can be widely used for the fields of high-power microwave transmitting, high-power microwave transmitting, electronic countermeasure, phase control radar and the like.

Description

technical field

[0001] The invention relates to the field of high-power microwave transmitting antennas, in particular to a reconfigurable phased array antenna with left and right circular polarization. Background technique

[0002] High Power Microwave technology (High Power Microwave) is a new subject field derived from nuclear technology. It is a comprehensive subject combining pulse power technology, relativistic electric vacuum devices, antenna technology and other disciplines. Among them, the role of the high-power microwave antenna is to directional launch the high-power microwave generated by the relativistic electric vacuum device into space, which plays a key role in the high-power microwave system.

[0003] In order to enable high-power microwaves to have fast beam scanning capabilities, Southwest Jiaotong University proposed a phased array technology based on short helical antennas, but once the circular polarization direction of the antenna is designed, it canno...
