Abstract :
A comprehensive theoretical and experimental study of straight and bent coplanar waveguide (CPW) shunt stubs is presented. In the theoretical analysis, the CPW is assumed to be inside a cavity, while the experiments were performed on open structures. A hybrid technique has been developed to analyze the CPW discontinuities which has been proven to be accurate, since the theoretical and experimental results agree very well. Throughout this study, the effect of the cavity resonances on the behavior of the stubs with and without air-bridges was investigated. In addition, the encountered radiation loss due to the discontinuities was evaluated experimentally.<>
