“…With the advantages of low profile, low loss, low interference, and easiness of integrating with planar circuits, SIW has been proposed to design many high‐quality microwave and millimeter wave components, including filters. Advanced techniques and innovative structure features have been reported in some literatures to realize wideband SIW BPFs . A SIW filter in zigzag topology for ultra‐wideband applications was proposed with 28% bandwidth in Ref.…”

In this article, a novel design way of wideband bandpass filter (BPF) is proposed. A hybrid sharing waveguide based on spoof surface plasmon (SSP) and half‐mode substrate integrated waveguide (HMSIW) is developed. With low‐pass feature of SSP and high‐pass feature of HMSIW, the proposed waveguide is a BPF naturally and the filter bandwidth can be controlled by adjusting parameters easily. A filter sample is fabricated for verification and the measured 3‐dB bandwidth is 46%. The proposed new concept of filter design is attractive and can be used to develop different wideband BPFs.

“…The literature includes reports on various types of miniaturized techniques, such as evanescentmodes [1][2][3][4][5][6][7][8], dual-modes [9][10][11], SIW (substrate integrated waveguide) [12][13][14], SIR (stepped impedance resonators) [15,16]. Unfortunately, most studies focus on the realization of components at L-band or higher.…”

Abstract-This paper presents a novel miniaturized multi-evanescent-mode resonator. The resonator is achieved with a coaxial cavity. This coaxial cavity essentially has a direct short connection at one end and is connected with several lumped capacitances at the other end. The key technology of the resonator is the usage of multiple evanescent-modes of TM (transverse magnetic wave) modes. Due to the combined effects of the evanescent mode and multiple modes, the size of the resonator is greatly reduced. In this paper, the theory of resonator is discussed in detail. To verify the correctness of operation, the resonator is used in experimental measurements conducted to realize a third-order bandpass filter based on SIW (substrate-integrated waveguide) technology. The measured results are found to agree with the theoretical values.

“…Elliptic and quasi-elliptic bandpass filters with cross coupling are standard solutions to filtering specifications involving sharp selectivity, low in-band insertion loss, and high out of band rejection [5,6]. However, both the unloaded Q-factor and the dimension of a SIW cavity decrease with increasing frequency.…”

Two substrate integrated waveguide (SIW) pseudo-elliptic bandpass filters are presented that utilize higherorder mode cavities. In the first filter, two full-wave TE 102 resonators and two fundamental TE 101 resonators in a compact structure are properly coupled to generate two transmission zeros in a four-pole SIW filter. The coupling matrix of the structure with a centre frequency of 10 GHz and 200 MHz bandwidth is designed, and good agreement is achieved with simulations of two commercially available field solvers. In the second topology, by using symmetric inductive discontinuities and two rectangular SIW cavities, TE 102 and TE 301 modes are excited and generate two transmission zeros, one on each side of the passband. This dual-mode SIW filter with a centre frequency of 10 GHz and bandwidth of 300 MHz has been prototyped, and the measured data are in good agreement with results obtained from the coupling matrix and CST Microwave Studio.Index Terms -Substrate integrated waveguide (SIW); transmission zero; bandpass filter; pseudo elliptic filter; dualmode filter; coupling matrix.
