Abstract
A reconfigurable tri-mode resonator and its application to tri-band bandpass
filter have been demonstrated. The proposed filter exhibits 32.8%
fractional tuning range of the first passband from 1.12-1.56 GHz and 12.73%
of the third pass-band from 2.50-2.84 GHz, and a fixed second passband at 2
GHz, respectively. The first and third frequency passbands can be tuned
independently without interfering with each other. Especially, the filter
uses a hybrid technique of lumped inductors and microstrip lines, resulting
in a very compact mechanical size of 0.12 ?g ? 0.08 ?g, where ?g is the
guided wavelength on the substrate at the central of the first passband
frequency. The measured results agree well with the simulated ones.
