Abstract :
A 330-500GHz (WR2.2) directional coupler is demonstrated. The coupling is achieved by parallel quarter-wavelength gold beams suspended in air over a silicon substrate. The circuit was designed in an “H” shape in order to transition to low loss rectangular waveguide. We present the design and analysis of a WR2.2 coupler with 4dB insertion loss, 10dB coupling factor and 20dB minimum isolation. The techniques we describe can be employed to design high performance, low cost THz components.
