Özet

The ultra wideband (UWB) antenna is one of the essential part of vital sign detection radar systems. The antenna characteristics of high gain and reduced side lobe level have a contribution to improve the detection capability of the UWB radar. In this work Antipodal Vivaldi antenna backed with frequency-selective surface (FSS) is developed for UWB pulsed radar system in the frequency range of 3.1 to 4.8 GHz. The frequency-selective surface reflector is used to improve the gain of the antenna and reduces the side lobe level of the antenna. Substrate used for Vivaldi antenna and FSS is low cost material, FR-4 with a relative permittivity (εr) of 4.3 and a thickness of 1.52 mm. The air gap between the antenna and the FSS and the unit cell number of the FSS were optimized for high gain. The proposed FSS integrated antenna provides a maximum gain of 9.58 dBi. The prototype the antipodal Vivaldi antenna is fabricated and tested and the simulation results are verified using experimental measurements.
