PPDW has been proposed as a basic terahertz transmission line for its remarkable simple structure and comparatively low attenuation at terahertz frequency band. It can be applied to design many terahertz components. In this paper, a (3N + 3/2) × lambda circumference PPDW rat-race hybrid coupler operating at quasi-TE10 mode is studied. The investigation results show that, at 0.34THz, the transmission losses of the two split output ports are both equals −3.2dB; the return loss at its input port is below −20dB; the insertion loss at each split transmission port is less than 0.2dB; and the two isolated ports show good isolation of above 20dB. Therefore, it will have wide potential applications at terahertz frequency band.
