Abstract: Provided is a folded dipole antenna including a meander line formed on a photoconductive substrate, characterized by an input impedance of several kΩ, which is much higher than that of a conventional dipole antenna, due to optimization of a horizontal length, a line interval, a width, and a line number of the meander line. Accordingly, use of the folded dipole antenna greatly improves an impedance matching characteristic between the antenna and a photomixer having an output impedance of 10 kΩ or more, and accordingly an output of a THz continuous wave.
