Abstract :
Novel horn antennas incorporating Sievenpiper high-impedance electromagnetic surfaces are shown in the following work to provide a reduction in volume. Functioning as TEM horn antennas, they operate at geometries that would otherwise be below the TEio cutoff frequency and are capable of carrying more power than microstrip antennas with equivalent volumes. Four antennas in two geometries with metal and HIS sidewalls are designed, measured, and compared.
