Single-Layer Series-Fed Planar Array with Controlled Aperture Distribution for Circularly Polarized Radiation

We propose a compact circularly polarized series-fed patch array with enhanced radiation performance at S-band. To our best knowledge, no similar single-layer structure has been designed, measured, and reported in the literature with equivalent radiation performances in terms of reduced sidelobe level (SLL) and aperture efficiency as well as compactness and simplicity. The planar array consists of...
