“…Filter is one of the key components, so, not only the performance requirements of the filter are greatly improved, but also the demand for their dual-band frequency response characteristics is increased. Therefore, dual-band bandpass filters with good performances and compact sizes have great development prospects [1,2,3,4,5,6,7]. There are plenty of methods that can be adopted to realize the dual-band performance.…”

A dual-band bandpass filter using coplanar waveguide (CPW) has been proposed in the paper. To generate the first passband, a gap is adopted in the central strip of the CPW main transmission line, and two pairs of spiral-shaped defected ground structures (DGSs) are added to the ground planes. Then, the loaded four L-shaped slots in the central strip of the CPW main transmission line can achieve the second passband. The measured central frequencies of the dual-band bandpass filter are 3.59 GHz and 5.87 GHz. The proposed filter has good dual-passband performance and good stopband suppression.

“…Easy design, simple layout structure, and the flexibility to control the central frequency and corresponding bandwidth, as well as size miniaturization, are the ongoing research trends for microwave bandpass filters (BPFs) to meet the increasing demands of emerging wireless applications. The split-ring resonator (SRR), which was originally proposed by Pendry [1], has demonstrated advantageous features of small electrical size, and easy design and synthesis, and therefore, has emerged as a front-runner for developing high-performance BPFs [2], [3]. Furthermore, its shape can be easily modified and a complementary SRR can be internally embedded to develop BPFs with good performance.…”

This paper presents a high-selectivity compact microstrip bandpass filter (BPF) with a flexibly controllable bandwidth, based on multi-path source-load couplings and a square-type split-ring resonator (STSRR). An STSRR, which is enclosed between the capacitively coupled source and load transmission feed lines, forms the structure of the proposed BPF. The main advantages of the proposed BPF lie in its simple structure and high selectivity due to multiple transmission zeros generated by multipath source-load couplings based on STSRR-enabled magnetic coupling between the feed lines with dual capacitive couplings. In addition, the bandwidth of the proposed BPF can be flexibly controlled by varying the magnetic coupling gap between the STSRR and the feed lines. The measured pass-band insertion and return loss of 0.83 and 27.23 dB, respectively, for a prototype BPF with a central frequency of 3.83 GHz and corresponding bandwidth of 12.98%, demonstrate the validity of the proposed method.

A compact triple-band high-temperature superconducting (HTS) YBa2Cu3Oy microstrip bandpass filter using multimode split ring resonator (SRR) is presented in this letter. Also, its properties and equivalent circuit models are investigated by even- and odd-mode analysis. Moreover, design method of the proposed triple-band HTS filter for the applications of global positioning system at 1.57 GHz, worldwide interoperability for microwave access at 3.5 GHz, and wireless local area networks at 5.8 GHz is discussed. The centre frequencies and the bandwidths of the three passbands can be allocated properly choosing the dimension parameters of the multimode SRR. In addition, four transmission zeros are produced to improve the selectivity of this filter.
