Abstract :
The influence of the grounded dielectric substrate finite size on the surface-wave propagation in a microstrip patch antenna is investigated. A simple model that interprets this phenomenon is developed. To reduce surface mode levels and to improve the antenna gain and the radiation pattern, an electromagnetic bandgap structure consisting of a two-dimensional periodic pattern of circles etched in the ground plane of the antenna is adopted.
