Abstract
An antenna for a ground-penetration radar system is disclosed. The antenna has a housing that defines a cavity. A radiator is located on a surface of a planar substrate within the cavity and is connected to a transmission line balun formed on the planar substrate. A wear-block is located between the radiator and the opening to the cavity for providing mechanical protection to the radiator. An absorber assembly is located on an opposite side of the radiator from the opening. The absorber assembly comprises a microwave absorber and a first dielectric layer. The first dielectric layer is located between the radiator and the microwave absorber.
