This paper is concerned with four different types of resonant antennas on semi-infinite substrates made of high-permittivity dielectric materials. Full-wavelength single-dipole, full-wavelength dual-dipole, half-wavelength single-slot, and full-wavelength four-leaf-clover-shaped dipole antennas are studied at a frequency of around 1.0 THz. The overall performance of four resonant antennas in terms of input impedance and radiation characteristics have been investigated and compared using the moment simulator FEKO.
