Abstract

This paper provides a novel method to steer the main beam of a patch antenna by partially covering it with a high-refractive index superstrate. The beam steering of a single patch is possible because of the dual-slot radiation mechanism of the microstrip antenna. Full-wave simulations have been employed to show beam deflections up to 37° in the presence of high-refractive index superstrates. Experimentally, a beam deflection of 25° is achieved when a microstrip patch is partially covered with a superstrate having a dielectric constant of 10.
