The prototypes of X-band active integrated antenna array for a satellite on-board tracking system

Abstract

Microwave components, prototypes of 4×4 transmitting active integrated antenna array(AIAA) and 2×2 receiving array with direction of arrival function operating at the X-band were demonstrated in this paper. For the components of the satellite on-board tracking system, a wideband and high gain low noise amplifier (LNA) as well as the compact planar antenna were fabricated using thin substrates. High isolation between the transmitting signal and the receiving signal was achieved for the good satellite tracking system. Good agreement on measured antenna patterns with the theoretical ones was obtained.
