摘要：
A novel compact quarter-wavelength resonator filter using the lumped coupling elements is presented in this letter. The filter not only has controllable transmission zeros near its pass-band, but also features compact circuit size. Based on the equivalent circuit model, a bandpass filter with the center frequency of 1.85 GHz has been designed and fabricated. Measured results have validated the theoretical analysis well.
