AB  - Satellite communication has received much attention as one of the key technologies of next-generation communication systems. The most distinguishing property of satellite communication compared to terrestrial communication is that the connection between the transmitter and receiver is primarily line-of-sight (LOS). The array pattern, which is the spatial response of the antenna array in a LOS environment, determines the beamforming gain and interference suppression level for a given beamformer. Accordingly, the beamformer optimization problem boils down to array pattern synthesis, which greatly simplifies system design. In this paper, we provide a concise review on phased array theory and numerical array pattern synthesis methods.
