Abstract
A method of balancing the bandwidth of a dual-mode filter, consisting of a ring resonator produced by microstrip technology, removes strip material in one or more places on the ring resonator where the first of the two modes of the ring resonator has a maximum current intensity, and in one or more additional places on the ring resonator, where the second mode has a maximum current intensity.
Claims11
A method of balancing a bandwidth of a dual-mode filter having a ring resonator made of a strip having a width, the method comprising the step of:
- narrowing the width of the strip at a first site at which a first mode of the filter has a current maximum, and at a second site at which a second mode of the filter has a current maximum.
