In this paper, we perform a detailed study of the input impedance of dielectric horn antennas with a two conical plate transmission line as a launcher, using the finite-difference time-domain (FDTD) method. Dielectric antennas are well known for having properties such as increased directivity, reduced sidelobe level, and wide bandwidth. These properties are particularly attractive for ground penetrating radar (GPR) applications.
