Abstract

The performance of a bowtie antenna placed in the plane of a high-impedance ground plane (HIGP) is examined. The antenna and HIGP are individually optimized to operate at the same frequency. Computational results are presented for the antenna gain and input impedance. Additional results are presented in which the antenna input impedance has been matched to the characteristic line impedance through post processing of the data. The antenna gain, input impedance, and return loss are used as figures of merit to evaluate the effectiveness of an integrated HIGP antenna. Results show that the interaction between the antenna and HIGP shifts the intended resonant frequency and reduces the bandwidth.
