Abstract-In this paper, a novel compact tri-band bandpass filter (BPF) with compact circuit size and high passband selectivity has been presented and implemented using multipath-embedded resonator (MER). This filter includes two multipath-embedded stepped impedance resonators (SIRs), connected with stub-coupling at the symmetric plane. By tuning admittance ratio and length ratio of the multipath-embedded resonator, it can be designed at 1.84, 2.45, 3.05 GHz. Through internal edgecoupling and extemal zero-degree feed lines, a tri-band BPF can be achieved with compact circuit size, high passband selectivity and low insertion loss. The measured results validate the full-wave EM simulated results with good agreement.

Abstract-A compact tunable dual-band bandpass filter (BPF) based on substrate integrated waveguide (SIW) and defected ground structure (DGS) is investigated in this paper. The second passband can be flexibly controlled by changing the dimensions of the updown DGSs whereas the first passband is fixed. The proposed filter exhibits improved selectivity due to the introduction of four left-right DGSs generating transmission zeroes. To verify the design method, a compact dual-band filter with the second center frequency switched among 5.4 GHz, 5.8 GHz, 6.4 GHz and 6.8 GHz and the first center frequency fixed at 4.78 GHz, is designed and fabricated. The simulated and measured results are in good agreement with each other.

“…In [6], two dual-mode dual-band BPFs are proposed by using a frequencyselecting coupling structure with coupled lines at its input/output ports. So far, some advanced fabrication techniques have been used in dual-band filter development [7][8][9][10]. The techniques of integrated passive device (IPD) [7], multilayer lowtemperature co-fired ceramic (LTCC) [8,9], and multilayer organic substrate [10] are employed.…”

The techniques of integrated passive device (IPD) [7], multilayer lowtemperature co-fired ceramic (LTCC) [8,9], and multilayer organic substrate [10] are employed. Compared with the standard printedcircuit-board (PCB) technique, the fabrication cost of these four filters are relatively high.…”

Abstract-This paper presents two novel dual-mode dual-band bandpass filters (BPFs) by using stubs loaded coupled line. The analytical equations of their transmission poles and transmission zeros are given by the classical even-/odd-mode method. Design rules for two dual-band BPFs are also given, which show the easily tuned passband frequency locations and in-band performance. As examples, two dualmode dual-band BPFs, dual-band filter A with central frequencies (CFs) at 3.5/6.8 GHz and −3 dB fractional bandwidth (FBW) of 14%/10%, while dual-band filter B with CFs at 2.4/6.8 GHz and −3 dB FBW of 43%/16% are designed, fabricated and measured. Good agreement can be observed between the simulations and measurements. These two filters exhibit simple design procedures, simple physical topology, low insertion losses, good return losses, high isolation and compact sizes.
