Abstract: |
A filter of microwave in single folding has a structure which consists of a resonator array constituted by multiple resonators with the same structure. The resonator has the single folding structure formed by a microstrip line with a open end and a close end, and the said open end having microstrips at two sides in different lengths, the resonators are arranged in parallel with two and two in symmetry with the long edge at inside to form a hairpin shape of resonator set, the input and outupt coupling lines are connected with input and output feeder lines, and the input and output cooling line is coupled with the resonator which is the nearest by oneself in the above resonator array. In addition, it has another structure which is different from the above one, and the resonators are arranged sequentially in parallel and in the same direction. |
