Abstract

The sparse array feed and recently demonstrated near-field phase correction has been used together to design a high-gain resonant cavity antenna (RCA). The integration of two techniques yields an antenna with higher directivity and relatively smaller profile. The antenna has been designed by first using the sparse-array feed with classical RCA and then improving its aperture phase distribution using the near-field phase correction. The final design has a 2x2 array feed with the full ground plane, an unprinted partially reflecting surface (PRS) and an all-dielectric phase-correcting structure (PCS). The peak broadside directivity of this antenna at the operating frequency is 22 dBi. The peak directivity was increased by 7 dB due to sparse-array feed and further 2 dB was increased with the PCS.
