Abstract

A shaped-beam Transmit Array Antenna based on nonuniform dielectric layer is proposed. Stepping the surface of dielectric layer provides the required phase shift at each point on the surface of transmit array antenna to produce a squared cosecant beam on the other side. In order to analyze this kind of antennas, a simple method based on an equivalent circuit model is introduced, in which the transmission coefficient of each element for oblique incident field is obtained. The design process consists of two steps. First, a phase-only technique is applied to obtain the required phase-shift distribution on the surface of transmit array antenna which generates the shaped pattern. The second stage consists of determining the thickness of each element to achieve the phase distribution obtained in the previous step. Using this method a shaped beam transmit array antenna in the 9.5-10.5 GHz band is designed, manufactured and also validated by the Computer Simulation Technology (CST) Microwave Studio TM package. The results of test in an anechoic chamber, shows a good agreement between measured, simulated and theoretical radiation patterns.
