Abstract
This paper discusses the axial ratio (AR) response in the E-plane by the virtue of controlling the physical and electrical feed properties for the 1,3 and 5 element system excited by quadrature phased dual feeds. The single element is designed and formulation used for the desired AR. For beam steering, 3 and 5-element array system is setup in E plane and axial ratio (AR) response is studied and corrected for the beam steering ranging up to steer angle -60 degrees. The physical properties are changed in single antenna The best responses for the single antenna and array antennas are kept below AR less than 0.5 dB throughout the bandwidth of interest. The amplitude ratio and the phase difference for the quadrature phased dual feed is within 1.2-1.4 range for all the desired responses and the phase difference is ranging wide specially for the beam steered array system.
