Abstract :
An omnidirectional millimetre-wave antenna based on a cylindrical electromagnetic bandgap (EBG) resonator is presented. The cylindrical woodpile is fabricated using the ceramic extrusion freeforming technique with high purity alumina powder. The designed antenna can achieve a narrow beam with 6.5deg measured half power beam-width in the elevation plane without using an array configuration. The overall antenna gain is approximately 5degdBi at 94.2degGHz, suitable for future short range gigabit wireless communications.
