Abstract
This letter presents coplanar integrated directional couplers for 90 and 180 GHz with a 60-GHz (120-GHz) band- width and up to 20-dB directivity. A three-dimensional (3-D) field simulator has been used to calculate the complex propagation constants and the impedances of the two modes. For the first time, the comparison of simulated and measured -parameters up to 230 GHz shows the validity of the design approach and the capability of integrated coplanar couplers.Keywords
