S/L-frequency band planar self-tracking antenna

Abstract

The present invention discloses an S / L-frequency band planar self-tracking antenna. The S / L-frequency band planar self-tracking antenna comprises a radome, an antenna housing, an inner cavity supporting structure, an antenna array plane printed circuit board, an S-frequency band network printed circuit board, an S-frequency band antenna unit, an L-frequency band antenna unit, an S-frequency band network printed line, an L-frequency band network printed line, an S-frequency band sum-difference modulator and an S-frequency band low-noise filtering assembly; the S-frequency band antenna unit includes an S-frequency band orienting sheet, an S-frequency band radiation patch, an S unit supporting column and a feed pin; the L-frequency band antenna unit comprises an L-frequency band orienting sheet, an L-frequency radiation patch and an L unit supporting column; the S-frequency band network printed line is arranged at the lower surface of the S-frequency band network printed circuit board; the L-frequency band network printed line is arranged at the upper surface of the antenna array plane printed circuit board; and the S-frequency band sum-difference modulator and the S-frequency band low-noise filtering assembly are installed at the lower surface of the inner cavity supporting structure. The S / L-frequency band planar self-tracking antenna of the invention has the advantages of decreased size, reduced weight and improved gain.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an S / L frequency band flat panel self-tracking antenna. Background technique [0002] At present, domestic telemetry ground receiving stations generally use parabolic reflector antennas with high gain to track flying targets. However, parabolic antennas have the disadvantages of high development cost, large size, and inconvenient use in mobile or portable telemetry receiving stations. [0003] With the development of technologies in communication, navigation, remote control and telemetry in our country, the application and development of the "communication in motion" communication system is very rapid. The existing parabolic antenna can no longer fully adapt to the new requirements. [0004] The panel antenna has the advantages of small size, low profile, and light weight. Under the same gain requirements, the size is significantly smaller than the parabolic antenna, and it is...
