Abstract :
This paper presents the design of a new type of Yagi-Uda antenna that operates in the terahertz frequency region. This antenna achieves a high input resistance of approximately 2600 Omega at the resonance frequency by using a full-wavelength dipole as the driver element instead of a half-wavelength dipole. The output power of this antenna is expected to be appreciably greater than that of existing terahertz photomixer antennas.
