Abstract

In ground penetrating radar (GPR) system, antennas are usually situated very close to the ground surface. Characteristic of the antenna is strongly influenced by the type of the soil. Antenna with stable impedance matching is needed to achieve a good system performance. A printed UWB monopole antenna with adaptation capability is proposed for stepped frequency continuous wave (SFCW) ground penetrating radar (GPR) application within frequency range 100-1000 MHz. The UWB monopole antenna consists of a hexagonal strip line with resistive loading and a rectangular slot that is added at the ground plane side of the printed UWB monopole antenna. Resistive load adjustment is applied for controlling the antennas input impedance due to the problem of varying soil condition. This paper presents the simulation investigation of the proposed antenna in controlling the matching condition.
