Abstract

A comparative analysis of two phase correcting structures (PCSs) is presented for an electromagnetic-bandgap resonator antenna (ERA). PCSs are made out of two distinct high and low permittivity materials i.e. Rogers O3010 and polylactic acid (PLA), respectively. Design and performance analysis is based on superstrate height profile, side-lobe levels, antenna directivity, aperture efficiency, prototyping technique and cost. Insertion loss for both superstrates is greater than 0.1 dB, assuring the maximum transmission of the antenna's radiations through the PCSs. The presented study is based on full wave analysis used to integrate sections of superstrate with custom phase-delays, to attain nearly uniform phase at the output, resulting in improved radiation performance of antenna. The peak directivity of the ERA loaded with Rogers O3010 PCS has increased by 7.3 dB, which is 1.2 dB higher than that of PLA PCS. In addition, the height of the PCS made of Rogers is 71.3% smaller than the PLA PCS. However, the former will involve fabrication complexities related to machining compared to the latter which can be additively manufactured in single step.
