Abstract

To obtain an adjustable passband filter, one open stub with three branches is loaded on an open loop resonator. The first and the third passband frequencies of the tri-band filter can be flexibly controlled by tuning lengths of three branches, whereas the second passband frequency is fixed. The fabricated filter has good tri-passband performance at 2.19, 4.26, 6.30 GHz. Measured results agree well with the simulated ones.
