Abstract

The invention discloses a solid plasma-based wideband variable-frequency antenna. The solid plasma-based wideband variable-frequency antenna comprises a solid plasma generator array (1), a substrate (2), biasing electrodes (3), a strut (4), a metal base (5), a wideband Balun (6) and a radio frequency connector (7), wherein the substrate (2) covers an upper port of the strut (4), the solid plasma generator array (1) is arranged on an upper surface of the substrate (2), a plurality of biasing electrodes (3) are connected to a part below the solid plasma generator array (1), the wideband Balun (6) is arranged in a cavity of the strut (4), an upper end of the wideband Balun (6) penetrates through the substrate (2) and is welded on the solid plasma generator array (1), and a lower end of the wideband Balun (6) is welded with the radio frequency connector (7) fixed at a part below the metal base (5). By the method, application in a frequency hopping radar and a frequency hopping communication system can be achieved.

Description

technical field [0001] The invention relates to a frequency conversion antenna, in particular to a wideband frequency conversion antenna based on solid plasma. Background technique [0002] In modern radar, communication and other systems, making full use of frequency hopping signals can reduce the interception rate, enhance the ability of multiple access networking, and anti-jamming capabilities. The frequency conversion antenna is a necessary component for the system to realize the above functions. A variable frequency antenna generally includes a radiator, a feeder, a frequency switch and a radio frequency connector. The radiator is mainly used to generate electromagnetic waves and radiate into space, and the radiator of the variable frequency antenna can radiate electromagnetic waves of different frequencies within a certain frequency band. Since the structure and form of the commonly used metal radiators are relatively determinate, that is, they have determinate frequ...
