Figure 1

A miniature circular microstrip array. The center frequency of each right-hand circular polarized element is  GHz. The dielectric substrate has RDP of and LT of . The metal working platform is elliptical, with a  mm major axis and a  mm minor axis. The array’s radius is  mm, and the interelement spacing is  mm. Each antenna is set at an inclined angle of on the workbench.
