This paper describes the design and the high performance of a new balanced antipodal Vivaldi antenna for ultra‐wideband applications. The return loss, radiation pattern, antenna gain, and level of cross polarization of this antenna are presented for both simulated and experimental results. The antenna is demonstrated to have greater than decade bandwidth (impedance within 10 dB over 1.3–20 GHz) and low cross polarization (<−17 dB in the broadside direction) over the band. © 1998 John Wiley & Sons, Inc.
