The design of a square-ring microstrip antenna with circular polarisation (CP) is presented. To compact the antenna size and overcome the high impedance problem, the CP antenna is excited by a coupling strip located inside the square-ring patch. Several prototypes of the squarering CP antennas with various substrate thickness (0.013-0.09λ0) have been constructed and studied experimentally, and their coupling-strip designs and CP performance are described.
