Abstract

Beam steering antennas are advanced technologies used for directing radio waves in a specific direction without physically moving the antenna. In this paper, a simple two steering beams antenna is designed based on Fabry-Perot structure. The amplitude and phase control theory is introduced to design the electric field phase and electric field strength in the near field to obtain the far-field radiation pattern required for the Fabry-Perot antenna (FPA). The FPA working at 10 GHz with the aperture of 5λ₀ × 5λ₀ steers to ±30° with the maximum gain of 18 dB for each beam realized by a proper design of the superstrate, which is a key to realizing a beam-steering antenna with a simple structure.
