Abstract

The invention discloses a solid plasma-based polarized reconfigurable antenna, which comprises a solid plasma generator array (1), a substrate (2), bias electrodes (3), a support column (4), a metal base (5), a feeder (6) and a radio frequency connector (7), wherein the solid plasma generator array (1) is formed by radial arrangement of a plurality of solid plasma generators or annular arrangementof a plurality of concentric circles or combination of two arrangement modes; the substrate (2) covers an upper port of the support column (4); the solid plasma generator array (1) is arranged on theupper surface of the substrate (2); the lower part of the solid plasma generator array (1) is connected with a plurality of bias electrodes (3); and the upper end of the feeder (6) is welded on the solid plasma generator array (1) and the lower end is connected with the radio frequency connector (7) fixed at the lower part of the metal base (5) through welding. The solid plasma-based polarized reconfigurable antenna can be applied to a multi-polarization radar and a communication system.

Description

technical field [0001] The invention relates to a polarization reconfigurable antenna, in particular to a polarization reconfigurable antenna based on solid plasma. Background technique [0002] In modern radar and secure communication systems, making full use of the polarization information of signals can improve detection and identification capabilities, increase channel capacity, and enhance anti-interference performance. The polarization reconfigurable antenna is a necessary part of the system to realize the above functions. A polarization reconfigurable antenna generally includes a radiator, a feeder, a polarization switch and a radio frequency connector. The radiator is mainly used to generate electromagnetic waves and radiate into space, and the radiator of the polarized reconfigurable antenna can form at least two kinds of radiated electromagnetic waves with different polarizations. Since the commonly used metal radiator has a definite structural shape, and corresp...
