Abstract

There is provided an improved filter having resonators substantially disposed between conductive planes which form one or more loading capacitors that are in turn coupled to the resonators. Further, inclusion of a designed void or slot in one or more of the conductive planes allows for control of an introduced transmission zero to manipulate the performance of the filter to achieve desired results, such as improved skirt performance.
