A new C‐shape slot cut square microstrip antenna is proposed for circular polarization (CP) using an aperture‐coupled feed. The C‐shape slot cut square microstrip antenna is fed at the center using an aperture coupled to get CP operation. About 4.3% measured 3‐dB axial ratio (AR) bandwidth with 13% 10‐dB return loss bandwidth is achieved. The overall antenna size is 65.0 mm × 65.0 mm × 11.5 mm. The proposed technology can be used to design low‐cost, compact, broadband circularly polarized microstrip antennas and arrays. © 2008 Wiley Periodicals, Inc.
