Abstract

A simple 3D printable meta-structure is proposed for use as a partially reflecting surface (PRS) in resonant cavity antennas (RCAs). The meta-structure acts as a spatial phase transformation device placed in close proximity above the RCA, thereby improving its gain by nearly 3dB. The aperture efficiency of the RCA with the proposed 3D printable PRS is 39%, with a half-power directivity bandwidth extending from 11.6 to 12.3 GHz. Material properties of ABS-M30 plastic filament are used in this preliminary design and numerical studies, making the PRS suitable for rapid prototyping using commonplace 3D printing methods.
