This paper outlines a new polarization reconfigurable EBG (Electromagnetic Band\nGap) antenna in the 60 GHz millimeter waves band. The proposed hybrid antenna is\ncomposed of a multilayer pyramidal DRA (Dielectric Resonator Antenna) exciting\nsource covered with a FSS (frequency Selective Surface) superstrate. The device can\nswitch between circular and linear polarization by a simple 45Ã?Å¡ mechanical rotation\nof the pyramidal DRA. This structure has the advantage that it maintained stable\nbandwidth, gain, efficiency and radiation properties when switching between the two\nconfigurations of circular and linear polarization.
