| Abstract: | To describe the basic principle of evanescent waveguide bandpass filter,a narrow-band bandpass filter were designed.The filter have a central frequency of 3.65 GHz and 30 MHz bandwides.And the size of filter is only 37 mm×17 mm×7.5 mm,the insert loss is less than 6dB,and the return loss in the passband is less than-22 dB,stopband attenuation curve quite steep.Experiments demonstrate the design feasibility and correctness. |
