摘要: In this paper, a compact band-stop filter with wide bandwidth and far spurious stop band is presented. The traditional usually be designed 1/4 wavelength admittance/impedance inverter, its volume bulky near the working stop-band. for realizing miniaturization, band, capacitor loaded in filter's resonators trench dredged on surface of capacitors. At first, rectangle cavity proposed, 4.5 times than center frequency. Then several such cavities are connected series to form filter, stop-band centered at 5GHz, relative 8%, higher 23GHz. has transition 100 MHz attenuation up 40dB.
