Equiangular microstrip spiral antennas

Authors: null Shih-Chang Wu;

Equiangular microstrip spiral antennas

Abstract

The input impedance and the broadside axial ratio of a perturbed equiangular microstrip spiral antennas are examined. With the perturbation (modification factor /spl delta/) on its shape, the broadside axial ratio of the equiangular spiral can be significantly reduced. A 21% 3-dB axial ratio bandwidth has been observed. The antenna input resistance can be effectively changed by varying the spiral starting winding angle.
