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-variable antenna, in particular to a wide-band frequency-variable 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 multi-access networking capabilities, and anti-jamming capabilities. The variable frequency antenna is a necessary part of the system to realize the above functions. Frequency conversion antennas generally include radiators, feeders, frequency switching switches and RF connectors. Among them, the radiator is mainly used to generate electromagnetic waves and radiate to space, and the radiator of the variable frequency antenna can radiate electromagnetic waves of different frequencies within a certain frequency band. Since the commonly used metal radiators have a relatively definite structural shape and correspondingly have a definite frequency working stat...
