A compact low profile dual band reconfigurable antenna has been developed and discussed. The basic structure is derived from a circular SIW cavitywhich has been segmented along the quasi-magnetic walls to form the 64th Mode SIW. The ground plane has been engineered to obtain quasiomnidirectional radiation pattern. The end-wall is shorted by metallic vias. Two locations on the antenna structure have been shorted by PIN diodeswith suitable bias voltages. Dual mode operation at two different frequency bands has been successfully demonstrated. © 2017 IEEE.
