Development of Single Point Feed Circularly Polarized Coplanar Antenna

Abstract

A single point feeded circularly polarized coplanar antenna is proposed. The antenna shape composes rectangular slot loop antenna of 1λ (Wavelength) and the earth conductor. The antenna shows orthogonal surface currents and appropriate phase difference to generate the circular polarization wave. Antenna design method is studied and the design parameters table is obtained for several applications. Moreover, antenna performance are measured and examined with the numerical simulation results. Finally, the application for XMSR was examined with the car body model.
