“…In the single-filter architecture, the parallel-coupled microstrip BPF uses the stepped impedance resonator (SIR) to control the multiple resonances for synthesizing the second passband [3]. On the other hand, the N-band resonator consists of multiple open-ended shunt stubs to produce multiple transmission zeros for making multiple passbands [4]. For example, a single filter consisting of two dual-band resonators can realize dual second-order bandpass responses [5,6].…”

This paper presents a left-handed transmission line (LH TL) based dual-band resonator to implement the dual-band filter. The proposed resonator consists of one uniform LH TL and one right-handed transmission line (RH TL) to produce three transmission zeros at 52 GHz, 267 GHz, and 531 GHz. The perforated ground plane is applied to extend the operating bandwidth of the LH TL for covering the full bandwidth of the dual-band filter. A CMOS prototype is designed based on the proposed resonator, and measured through the on-wafer measurements. Both simulated and the measured results confirm the insertion-losses of 1.8 dB and 2.4 dB of two passbands at 186 GHz and 420 GHz. The statistic shows the total length of the proposed resonator is about 0.038 λ g at 52 GHz.

“…A section of transmission line is used as simple coupling circuit between triple-mode resonators for realizing triple-band bandpass filter with no limit in filter order [10], and specified bandwidths can be approximately achieved, but the passband flatness and return losses are poor since the transmission lines are not quarter-wave lines at all frequencies and cannot be regarded as ideal multi-mode J inverters. A so-called dual-behavior resonator [11] is acting as a multi-mode resonator and is only used to realize 1 st order multi-band filter, since lacking of multi-mode coupling elements.…”

A generalized circuit topology and synthesis method for multiband bandpass filters with controllable center frequencies and bandwidths are proposed based on a semi-hidden multi-mode coupling element. The socalled semi-hidden multi-mode coupling element is a Π-shape multi-mode J inverter constructed by a transmission line and two multi-mode capacitors at two ends, and the multi-mode capacitors are merged or hidden into nearby multi-mode resonators, modifying the equivalent LC circuits of the multimode resonators at the passbands. The multi-mode J inverter gets simplified and only a connecting line needs to be implemented, which simplifies highorder multi-band bandpass filter design. For validating the filter topology and synthesis method, the circuit and design example of triple-band bandpass filter are presented by using triple-stub triple-mode resonators, and a genetic algorithm is used for extracting the parameters of the triple-mode resonators. Good features including controllable bandwidths, high isolations are achieved.

“…The design of such filters is generally requires the realization of advanced filtering transfer functions; a topic that has resulted in many interesting contributions such as [1][2][3][4][5][6], just to name a few. Cameron et al [7] first introduced the box configuration which basically comprises four inverter-coupled resonators with only a single negative coupling branch.…”
