Abstract
A novel compact, low cost printed antenna with beam steering and gain enhancement capability is presented in this paper. The antenna is structured with a substrate for designing the radiator patch and a partially covered superstrate with appropriate air gap for steering the beam and improves the directivity, instead of relying on additional parasitic elements and phase shifters that increases the complexity of the design. The antenna is excited from the probe feeding point. Partially covering of radiator patch by a high refractive superstrate causes phase deviation in electromagnetic radiation. The antenna beam is able to cover up both E-plane and H-plane. This design is based on a new technique which may not have been implemented earlier. The antenna design and simulation is carried out using IE3D electromagnetic EM simulator and study of various parameters of the designed antenna is well explained in this paper. The gain is enhanced up to
