Two-Cavity Filter With Three Transmission Zeros

It is well known that an N-order coupling network with source-load coupling can realize a maximum number of transmission zeros equal to N. However, in the letter, by utilizing open-circuited stubs and increasing the velocity ratio, a novel two-pole hairpin filter can obtain three transmission zeros,...

Zusammenfassung:	It is well known that an N-order coupling network with source-load coupling can realize a maximum number of transmission zeros equal to N. However, in the letter, by utilizing open-circuited stubs and increasing the velocity ratio, a novel two-pole hairpin filter can obtain three transmission zeros, which can improve selectivity in the lower stopband. The filter is analyzed extensively by using the relations between the types of coupled microstrip lines and transmission zeros of transfer response. Good agreement between measured and simulated data has been demonstrated.
