- Abstract
- This paper presents the design of terahertz Yagi-Uda antennas with high input resistance. The proposed Yagi-Uda antennas can achieve much higher input resistance than existing THz antennas by using a full-wavelength straight-line dipole and a full-wavelength U-shaped dipole as driver elements. Current leakage into the bias line was minimized by applying photonic bandgap structures at the bias line. By designing the antennas on a thin substrate, end-fire radiation patterns with high antenna resistance can be obtained even when the substrate has a high dielectric constant. We expect that the proposed Yagi-Uda antennas can achieve increased terahertz output power by improving their capacity for impedance matching with a photomixer.
