Abstract :
Radiation losses are investigated for open coplanar waveguide (CPW) discontinuities by the space domain integral equation technique. Results are presented for CPW open-end and stub discontinuities. It is pointed out that, at submillimeter wave frequencies, CPW technology offers greater design flexibility over microstrip, but lags in the availability of design tools. The method presented here can be used to develop high-frequency circuit models. In addition, it can be used to realize low-loss designs as was demonstrated by the improved tuning stub layout.<>
