Abstract :
In this letter, a novel sharp cutoff Ka band waveguide filter is presented and fabricated for transmitting and receiving isolation of an application system, which stop band frequency deviates from pass band only 3% relative bandwidth. The proposed filter´ stop band frequency is verified by good agreement between simulation and measurement results. The measurement results show less than 1 dB insertion loss in pass band, and more than 70 dB suppression in stop band.
