A high gain planar antenna is proposed operating at W band. It is based on a Frequency Selective Surface (FSS) placed in front of a waveguide aperture in a ground plane. The FSS is printed on a thin quartz substrate which is supported on an SU8 polymer ring, forming an air cavity with the metallic ground. The geometry has been optimized using full wave simulations (CST Microwave Studio™). The antenna performance is based on the reflection characteristics of the FSS array. An antenna of around 25 dBi gain at an operating frequency of 94 GHz is obtained, suitable for imaging millimeter wave applications.
