Directivity Improvement of Low-Profile Electromagnetic Band Gap Resonator Antenna Using Phase Transformation Sheet
This study proposes an efficient method for directivity improvement of electromagnetic band gap (EBG) resonator antennas with enhancement of near-field phase distribution. A single dielectric layer phase transformation sheet (PTS) is designed at 11 GHz based on the operational frequency of the EBG resonator antenna. The PTS consists of two unit cells printed on both sides of a single dielectric layer to compensate for the non-uniform near-field phase distribution of the EBG resonator antenna. The proposed solution doubles the uniformity region of the phase distribution and achieves 22% aperture efficiency.
