This paper presents a new coupling design of circular polarization (CP) for annular-ring patch antenna with a simple microstrip feed line. Several annular-ring patch antennas with different relative permittivity and thickness of substrate are constructed and simulated for verifying the proposed CP coupling method. Details of the antenna design and the obtained experimental results of the antenna performance are presented and discussed.
