Abstract

The purpose of this study is to present a new design method to obtain broad/dual-band characteristics for circular polarization (CP) square slot antennas using GLS algorithm. By employing this proposed method, optimum impedance and axial-ratio bandwidths for any given operating frequency can be achieved without using the trial and error method. The antenna prototypes are constructed and measured to provide validation of the design method.
