Abstract

In this paper, we present an antenna which can be used for subsurface continuous wave electromagnetic probing. Its input impedance and transmission coefficient of the two port scattering parameters, S$_{21}$, are calculated numerically and the numerical results are compared with measured values from laboratory scale-down experiment. Scale-down experiemtn results using this antenna show that we can detect a metallic pipe, which has 0.8 cm in diameter and buried at a depth of 5.7cm in saline solution, in frequency range from 200 MHz to 1000 MHz.
