A planar surface wave antenna (PSWA) that realizes a bidirectional radiation pattern with a low profile configuration is designed, fabricated and measured. The antenna consists of a planar dielectric slab loaded with periodic spiral patches and EBG structure, which are designed to support the propagation of the surface waves in the desired direction. The diffraction of surface waves at the edges of the ground plane generates a bidirectional radiation pattern. The radiation mechanism and performance of the PSWA are described and simulated with commercial CST software. The proposed antenna with only 1.6 mm thickness is fabricated and tested, which resonates at 2.4 GHz. The antenna is especially attractive for telemetry applications because of its low profile and weight.
