A novel aperture-coupled circularly polarized square-ring patch antenna for wireless communication systems

A novel square-ring patch antenna is proposed for circularly polarized (CP) radiation. Four square-patches are added at the four angles of the square-ring patch for an aperture-coupled feed to produce CP radiation in the WLAN band. In the proposed design, two pairs of square-patch are etched orthogo...

Summary:A novel square-ring patch antenna is proposed for circularly polarized (CP) radiation. Four square-patches are added at the four angles of the square-ring patch for an aperture-coupled feed to produce CP radiation in the WLAN band. In the proposed design, two pairs of square-patch are etched orthogonally on the square-ring patch for frequency perturbation and antenna size reduction. Proper adjustment of the side length of the square-patch and aperture-coupling position will excite two orthogonal modes with 90° phase difference for good CP radiation. Simulated and measured results indicate that the proposed structure can achieve circular polarization.
