In this paper we present the design and analysis of Ka band array fed reflector antenna for satellite communication links. The design consists of curved reflector geometry of 0.8 m which is fed with five element linear array antenna operating at 20.2 GHz (Ka band). As satellite applications demand beam-steering with higher gain and narrow beam, we use and analyze electromechanical beam-steering, i.e. electronic and mechanical steering (Hybrid beam-steering), through array fed reflectors. To ensure good scanning capabilities the feed array is configured in horizontal as well as in vertical directions. A 2-D scanning of ±6 o is achieved when the feed element is placed horizontally in focal plane whereas ±3 o when the feed element is placed vertically in focal plane with the proposed array fed reflector. The proposed antenna maintains a constant performance throughout the scanning range which helps vehicular tracking and many other satellite applications.
