Design and optimization of the antenna applied for detecting the voids in tunnel lining by GPR

Abstract

In this paper, a new Antipodal Vivaldi antenna has been designed to be used for detection of the voids in tunnel lining by Ground penetrating radar (GPR). In order to obtain a desirable antenna performance, the wider impedance bandwidth, the higher radiation efficiency and gain, three parameters of the antenna structure, including a) length of microstrip… (More)
