Abstract :
In this paper, a novel bandpass filter using microstrip-via-CPW resonator is proposed. This symmetric resonator can support two modes. By introducing source/load coupling, two additional zeros can be generated. The whole structure was meandered for size reducing. Advantages of using this type of filter are not only its low insertion loss, but also its controllable transmission zeros. Both simulated and measured results are presented.
