ABSTRACT: This paper outlines a new polarization reconfigurable
EBG (Electromagnetic Band Gap) antenna in the 60 GHz millimeter waves band. The
proposed hybrid antenna is composed of a multilayer pyramidal DRA (Dielectric Resonator
Antenna) exciting source covered with a FSS (frequency Selective Surface) superstrate.
The device can switch between circular and linear polarization by a simple 45° mechanical rotation of the pyramidal DRA. This
structure has the advantage that it maintained stable bandwidth, gain, efficiency
and radiation properties when switching between the two configurations of circular
and linear polarization.
