Abstract :
We report a first demonstration of a transmit array with fiber-optic control for independent two-dimensional true time-delay steering. The 4/spl times/4 array consists of flared-notch elements and shows /spl plusmn/30/spl deg/ azimuth and /spl plusmn/30/spl deg/ elevation steering with no observed squint over the microwave component-limited bandwidth of 6-18 GHz.
