| Abstract: | An antenna ground plane (GP) plays a major role in the mitigation of multipath coming from underneath the antenna. A distinct
trend in user antenna size and weight reduction has been observed during recent years. With this focus in mind, an overview
of conventional flat conductive and impedance GP is provided. Results of modern developments of passive vertically stacked
structures are discussed. The possibility of obtaining a reasonable level of multipath mitigation with vertical structures
of several centimeters is shown. |
