Abstract

Planar microstrip patch antennas can achieve a wide range of radiation patterns. However, due to surface-wave losses, they have low bandwidth, low gain, and a potential decrease in radiation efficiency. In order to minimize the surface-wave effects, a photonic-band gap (PBG) substrate is proposed. The PBG structure significantly diminishes the surface wave modes and thus improves the gain and farfield radiation pattern and efficiency. In this paper, using FDTD, an accurate full wave analysis of surface wave propagation in a rectangular microstrip patch antenna with and without PBG is presented.
