In this paper, the research advances in SIW-like (Substrate Integrated Waveguide-like) guided wave structures and their applications in the State Key Laboratory of Millimeter Waves of China is reviewed. Our work is concerned with the investigations on the propagation characteristics of SIW, half-mode SIW (HMSIW) and the folded HMSIW (FHMSIW) as well as their applications in microwave and millim...

A simple method for designing a triple-mode bandpass filter is presented in this paper. Triple-mode is achieved by using half-mode substrate integrated waveguide (HMSIW) cavity. Three perturbation metal vias were introduced for shifting resonant modes. The resonant frequencies of these modes can be adjusted by the location and the diameter of perturbation vias properly. In order to improve the ...

A compact balanced UWB bandpass filter (BPF) is proposed in this paper, which is based on the half-mode substrate integrated waveguide (HMSIW) and the differential defected ground structure (D-DGS). Using the HMSIW, the filter can achieve compact size, wide passband and good compatibility. Two D-DGS cells are employed to provide good suppression for the common-mode (CM) noise, while they have s...

An approach for improving the gain of leaky-wave antenna (LWA) is presented in this paper. Embedding cavities structure leads to improvement. To validate proposed method, it was implemented on a half-mode substrate integrated waveguide (HMSIW) LWA. The HMSIW LWA realized low temperature co-fired ceramic (LTCC) achieve compact structure. key novelty improvement by using embedded without increasi...

A novel filtering magic-T (FMT) with a compact size, broad bandwidth, and wide stopband rejection based on the dielectric-covered L-shaped groove (DCLSG) half-mode substrate integrated waveguide spoof surface plasmon polariton (HMSIW-SSPP) structure is proposed for first time. HMSIW (HMT) dual-layer substrates designed. Then, we construct FMT by periodically etching subwavelength DCLSG SSPP int...

This letter proposes a multi-passband half-mode substrate integrated waveguide (HMSIW) filter based on the theory of odd and even mode analysis. The adopts triangular HMSIW cavity cut along diagonal rectangle. By etching two dual-mode resonators, resonant resonator is coupled with odd-even to achieve multiple passbands. defected ground structure (DGS) can reduce resonance frequency without incr...
