Abstract

A new circular-polarization (CP) design of an annular-ring microstrip antenna operating at the fundamental TM₁₁ mode is presented. The CP radiation of the proposed design is achieved by connecting an L-shaped strip to two orthogonal sides of the inner boundary of the annular-ring patch. A prototype of the proposed antenna fabricated on a foam substrate has been implemented and studied. The results show that good CP-radiation performances are obtained and the 3-dB axial ratio is about 2%. Good agreement is also obtained between the measured and simulated results.
