Enhancing Radiation Pattern Performance of the Cavity-Backed Lightweight Patch Antenna for Spacecraft Uses

This paper summarizes experiences we have gained in the area of optimization radiation pattern for the cavity backed patch antenna. The antenna is to meet user requirements for high data rate links operating between satellites and Earth. The antenna had been technologically developed up to the space standards and has been installed on ESEO microsatellite. The antenna electrical performance has been accomplished and at the same time the antenna mass was kept very low, robustness against space environment effects have demonstrated outstanding strength during testing.
