Abstract

We present to antipodal tapered slot antennas: one with elliptical strips termination and the other modified with elliptical shaped corrugations. Compared to the other, the corrugated antenna uses elliptical slots loading to improve the gain by up to 1.9 dB over operational bandwidth 0.8-18 GHz. It also improves the front to back lobe ratio. The simulated frequency and time domain results are in good agreement with measured performance of both antennas. Experimental results verify a fidelity factor greater than 0.86 for both antennas by transmitting 30ps (3-18 GHz) Ultra-Wideband (UWB) pulses.
