Cylindrical woodpile antenna for millimeter-wave short range gigabit communications

This paper presents a demonstration a resonator antenna based on the cylindrical woodpile EBG structure for applications at millimetre wave frequencies. The designed cylindrical EBG structure has been fabricated using the ceramic extrusion freeforming technique. Experimental results confirmed that the designed antenna showed narrow beam in the horizontal plane making the antenna useful for short range gigabit wireless communications at millimetre-wave frequencies. Precise fabrication of the structure is required for desirable omni-directional performance.
