Abstract

The paper presents a 3D printable all-dielectric phase-correcting structure (PCS) design. The PCS is based on concepts of full wave analysis of RCA and near-field phase correction. For the demonstration, the PCS is designed for a resonant cavity antenna (RCA). The phase correction is achieved by simultaneous variation of permittivity and height of the dielectrics. The dielectric arranged such that the surface converts spherical phase fronts of RCA to a nearly planar phase fronts. The structure is highly transmitting with insertion loss < 1.0 dB. The PCS improves the radiation performance of the RCA including a 5 dB increase in the broadside directivity (from 16.1 dBi to 21.1 dBi) and 23.8% enhancement in aperture efficiency has been achieved.
