Abstract
A terahertz dipole antenna grown on a photonic-bandgap (PBG) GaAs substrate is presented. The desired PBG structure is utilized to reduce the thick GaAs substrates effects on the efficiency and the main beam direction. Simulated results show that a directivity of 8.7 dBi can be achieved in the upper half space with a considerably higher input impedance.
