Abstract

This paper presents a new unit to design dual linearly polarized reflectarray antenna at ku for satellite telecommunication. Two orthogonal sets of parallel dipoles are used for each polarization to achieve more degree of freedom in the design and wider phase variation in the unit cells, consequently. A 0.3m Reflectarray Antenna with two distinct beams is fabricated and measured in an anechoic chamber. The measurements have been carried out for both polarizations (X and Y ) in the azimuth and elevation planes. This antenna has x-polarized beam at (θ0=30º, ϕ0=90º) with 23.7 dBi gain and y-polarized beam at (θ0=30º, ϕ0=0º) with 24.2 dBi gain at Ku-band. The proposed design has one layer and simple structure compared to the references as well as dual band and dual polarization capabilities.
