A Compact Vivaldi Shaped Partially Dielectric Loaded TEM Horn Antenna for UWB Communication by Mustafa İlarslan, A. Serdar Türk, Salih Demirel, M. Emre Aydemir, A. Kenan Keskin

“…Ultrawideband (UWB) antennas are of huge demand and Vivaldi antennas as well as the TEM horn antennas are good candidates for UWB applications as they both have relatively simple geometry and high gain over a wide bandwidth. The aim of this study is to design a compact antenna that achieves maximum gain over a bandwidth between 1.5 and 10.6 GHz while minimizing its size. …”
