Abstract
A novel monolithic implementation of a Wu-King profiled antenna intended for use in critical time-domain/UWB/imaging applications is presented. The simulated device was fabricated on a high-resistivity Si substrate on top of which a layer of GaAs is grown, segmented and patterned to serve as the radiating element. The device's measured return loss indicates a -10 dB BW > 50 GHz and time-domain measurements using a 500 pS input pulse prove that the device is practically non-reverberant in air. © 2008 IOP Publishing Ltd.
