Abstract
Dual-mode resonators have been widely investigated to realize RF/microwave filters. An attractive feature of this type of resonator is that each dual-mode resonator can be used as
a doubly tuned resonant circuit. This reduces the number of resonators required for an n-degree filter to half, resulting in a compact filter structure for light weight, small size and low
cost applications.
Conventional dual-mode resonators include circular disk, square patch, circular ring, square loop and meander loop, with a small perturbation applied to the resonator at a location 45 degrees offset from its two orthogonal modes. The coupling between the two modes is determined by the size of the perturbation element added to the resonator. Although
dual-mode resonators have been widely investigated, very few dual-mode resonator filters of the order of four or more have been reported.
Recently, there has been considerable interest in using composite-right/left-handed transmission line (CRLH) in dual-mode ring resonators. This is a relatively new idea, where coupling between the two modes is determined by the degree of mismatch between the composite lines. Besides, the main advantage of using a composite line in a ring resonator is
the suppression of the second harmonic. This paper reports the design of a new 4-pole dual-mode resonator filter with a Chebyshev response, based on earlier work.
