The low-profile phased array antenna with combined electrical and mechanical beam steering for satellite communications

The low-profile phased array antenna with combined electronic and mechanical beam steering (EMBS) in elevation plane is considered. Simulation results of investigated antenna are introduced (Fig. 2). Optimal antenna geometrical parameters allow keeping reasonable directional characteristics for scanning angles 0±70°. Comparison of a planar phased array antenna and a stair-planar array is performed and results are presented (Fig. 4).
