Abstract

The invention relates to a superimposed double-parabolic elliptical field antenna dedicated to a small-tilt synchronous communication satellite. The superimposed double-parabolic elliptical field antenna dedicated to a small-tilt synchronous communication satellite is divided into two parts along the axis, the first paraboloid and the second paraboloid. The focal axes of the first paraboloid and the second paraboloid form an included angle with the axis respectively; the superimposed double paraboloid elliptical field antenna dedicated to the small inclination synchronous communication satellite is provided with an elliptical horn waveguide, and the elliptical horn waveguide The orifice of the nozzle is set at the position including the focal point of the first paraboloid and the focal point of the second paraboloid. The antenna of the present invention covers the entire satellite drift track at latitude ±8°, so that the satellite ground station of the CAPS system for communication can adopt a fixed pointing antenna. The complexity of the ground antenna is reduced, and the antenna cost and maintenance difficulty are reduced.

Description

technical field [0001] The invention relates to a small inclination angle synchronous communication satellite superimposed double parabolic elliptical field antenna. Background technique [0002] The transponder on the synchronous communication satellite is used to forward the carrier signal modulated with the ranging code and navigation message transmitted by the ground navigation center station, and broadcast to the ground to realize the design concept of passive satellite navigation, which is the core principle of the CAPS system to realize positioning . The redundant transponder on the synchronous communication satellite of the CAPS system can also transmit the communication signal transmitted by the ground satellite communication center, which is the communication function of the CAPS system. [0003] The CAPS system changes the orbit position and attitude control of the fixed-point satellites on the earth, so that the synchronous communication satellites evolve into i...
