Abstract
To overcome the inexactitude and inconvenience of KQ method and parity module method, this thesis researches a designing method of terminal short-circuited microstrip interdigital filter based on self-mutual capacitance, gives detailed designing steps and example of simulation design. This paper puts forward an improved structure of microwave interdigital filter, this structure adds a microstrip line whose length is λ0/8. This structure makes the 3 dB bandwidth decrease from 100 MB to 40 MB, passband dithering decrease 2.7 dB, stopband attenuation decrease about 2 dB, this simulation result shows that this improved structure is in effect.关键词
