Transmission poles, and in that manner the number of resonators is reduced by half. As for multi-band filters, multi-mode resonators are used since they can provide passbands or stopbands at frequencies that are not harmonically related. 14 (a) Dual-mode microstrip resonator modeled as a cavity. (b) Equivalent circuit of the resonator. multi-mode resonators offer more design freedom when it comes to independent control of passbands. In addition, since multi-mode resonators support several modes, the size of multi-band filters can be significantly reduced.

Although the realization of four passbands gives greater design freedom in terms of combining single-band, dual-band, and even tri-band filters, all proposed quad-band filters except for [140] employ two dual-band filters. The filter in [140] employs a stepped-impedance resonator and a conventional halfwavelength resonator. The first passband is formed only by the fundamental mode and the half-wavelength resonator, whilst the other three passbands have two transmission poles, one originating from the SIR, and the other originating from the half-wavelength resonator.

9 Fabricated circuit of the dual-band filter proposed in [19]. shown that multi-band filters designed using classical filter design theory are realized by introducing transmission zeros into a previously synthesized wideband response. In other words, it can be said that the previous method and the method presented here share a common design approach. However, there is a key difference between the two approaches. Namely, in the previous method transmission zeros are due to couplings between non-adjacent resonators.
