Spaceborne Conformal TT&C Antenna

Abstract

The invention discloses a spaceborne conformal measurement and control antenna, which comprises an antenna cover, an antenna vibrator, a feed network and a structure main body, the antenna cover is fixed to the side wall of the structure main body to form a closed cavity, and the antenna vibrator and the feed network are fixed In the closed cavity, the antenna cover is an anti-radiation wave-transmitting cover; the antenna vibrator is composed of four bending vibrators, and the installation positions of the four bending vibrators are arranged symmetrically and uniformly, and the bending vibrators pass through the coaxial structure and the feed connected to the electrical network. Compared with the microstrip measurement and control antenna, the technical solution proposed by the present invention has the advantages of wide working bandwidth, high radiation efficiency, high polarization purity, large beam width, high gain at low elevation angle, and long life; compared with the traditional four-arm helical measurement and control antenna It has the advantages of low antenna height, embedded conformal design, firm structure, and easy production and processing.

Description

technical field [0001] The invention belongs to the technical field of communication antennas, and relates to a conformal measurement and control antenna, in particular to an embedded spaceborne conformal measurement and control antenna. Background technique [0002] In satellite antennas, in order to ensure the coverage of a wide pattern of measurement and control antennas, the antennas usually protrude from the surface of the satellite, and even increase the base to make the antenna higher than the surface of the satellite. In engineering practice, some satellites require the TT&C antenna to be invisible, and the TT&C antenna protruding or higher than the surface of the satellite cannot meet the requirement of invisibility. Therefore, a technical solution needs to be proposed to embed the satellite TT&C antenna into the surface of the star. If the existing measurement and control antenna is directly buried inside the satellite, the antenna pattern will become poor and cann...

Problems solved by technology

In engineering practice, some satellites require the TT&C antenna to be invisible, and the TT&C antenna protruding or higher than the surface of the satellite cannot meet the requirement of invisibility, so it is necessary to propose a technical solution to embed the satellite TT&C antenna into the surface of the star

If the existing measurement and control antenna is directly buried inside the satellite, the antenna pattern will become poor and cannot meet the requirements of measurement and control communication
