Design of a Novel Miniaturized Vivaldi Antenna with Loading Resistance for Ultra Wideband (UWB) Applications
Keywords:
ETSA, loading resistance, UWB antenna, Vivaldi antennaAbstract
A compact improved Vivaldi antenna working on 0.8-3.8 GHz was designed by using resistance-loaded and slotting technology. Resistance-loaded can reduce the plane size of antenna and three symmetrical unequal rectangular slots in the antenna radiation part can increase the gain. The improved Vivaldi antenna size is 150×150×0.508 mm3, which can be used in ground penetrating radar. The simulation results and experimental results are presented to validate the performance of the proposed improved structure of Vivaldi antenna.
