A method to enhance radiation characteristics by improving aperture phase distribution of electromagnetic bandgap resonators antennas

Research output: Chapter in Book/Report/Conference proceedingConference proceeding contribution

Abstract

Phase correction in the aperture field of electromagnetic band gap resonator antennas (ERAs) is discussed in this paper, with the objective of improving their directive radiation characteristics. A phase correcting structure (PCS) is formed by varying the height of a dielectric material, and improvements in radiation performance are investigated. The enhancement of aperture phase uniformity due to the PCS is significant. It resulted in an increase in the broadside directivity by 4 dB and reductions in side lobe levels by 3.5 dB and 6.4 dB in H- and E-planes, respectively.
