Abstract

Small array antennas with directive coverage are an attractive solution for size limitation in wireless devices. In this paper, the design of a directive 10 GHz antenna with reduced size microstrip array and frequency selective superstrate (FSS) is presented. Inductive loading and reduced patch separation is used to incorporate 7-elements within a 100x30 mm2 array aperture. The superstrate (FSS) layer is optimized to properly excite the Fabry-Perot cavity and further increase the antenna directivity. Using HFSS software, the reflection response and the radiation pattern of the antenna array is optimized. The simulated responses agreed well with the measured results.
