Abstract :
Simple models and a parameter extraction technique for low-cost SMD capacitors mounted on microstrip lines are presented. The models are simple networks, easily implemented in currently available microwave CAD (computer-aided design) programs. Their element values are obtained from the results of vector network analyzer measurements on microstrip structures. Therefore, the models include intrinsically mounting discontinuities. The transmission line parameters values are obtained from the first series self-resonance measured for a ground connection, and the RLC parameter values are obtained from parallel resonances measured with series connection
