An S-band multimode reflector antenna for a satellite constellation tracking system

A multimode reflector antenna is a new concept proposed by our team in recent years, which does not correspond to the use of the traditional multimode feed but to innovation in the reflector design. This paper presents an S-band multimode reflector antenna based on multimode reflector theory. To ach...

description A multimode reflector antenna is a new concept proposed by our team in recent years, which does not correspond to the use of the traditional multimode feed but to innovation in the reflector design. This paper presents an S-band multimode reflector antenna based on multimode reflector theory. To achieve a flat-top beam shape, the main reflector of the antenna is divided into a middle region and an edge region. The height difference between them is approximately λ(0)/4, and then, the reflected waves in different areas partially cancel out in the direction of maximum radiation. The voltage standing wave ratio of the antenna is less than 1.5 from 2.8 to 3.4 GHz (19.4%), and the gain is more than 29.2 dB in the same frequency band. At the same time, a good flat-top beam is achieved in the range of ± 2°. The antenna can be used for satellite constellation tracking and other systems that require high-gain flat-top beams.
