We have characterized the ON state DC electrical resistivity and OFF state capacitance of GeTe-Based RF Switches under direct optical laser excitation. Our tightly-coupled dipole array exhibits performance in excess of 4 to 1 bandwidth over wide-scan angle up to 60 degrees with in-band rejection capability using reconfigurable baluns. Integration of optically-controlled GeTe-Based RF switches at the antenna aperture extends reconfiguration flexibility.
