Compact filter solutions in substrate integrated waveguide (SIW) technology
2016 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM), 2016This paper presents an overview of the recent advances in the field of substrate integrated waveguide (SIW) filters with compact size. The proposed structures exploit different solutions to reduce substantially the footprint of the filters, including the use of folded SIW, half-mode SIW, and quarter-mode SIW cavities, as well as the use of mushroom ...

Multilayer Substrate Integrated Waveguide (SIW) Filters With Higher-Order Mode Suppression
IEEE Microwave and Wireless Components Letters, 2016This letter presents a multilayer approach for suppressing the higher order modes of substrate integrated waveguide (SIW) bandpass filters. Rectangular SIW resonators in multilayer substrates can be vertically coupled with magnetic and/or electric coupling by the proposed apertures etched on the middle metal layer.

Full-Band Air-Filled Waveguide-to-Substrate Integrated Waveguide (SIW) Direct Transition
IEEE Microwave and Wireless Components Letters, 2015A 45% bandwidth in-line air-filled waveguide-to-substrate integrated waveguide (SIW) direct transition is designed to greatly improve the performance of existing configurations. The transition, based on a four-section height-stepped waveguide, includes a single-step widening transformer that enables full-band operation without using any dielectric ...

In this paper, an iris waveguide filter with substrate integrated waveguide (SIW) structure at satellite communication band is discussed. The SIW structure is realized by via-holes on the substrate and shows a possibility of integration with other circuits. The iris waveguide filter has the insertion loss of 3.36 dB, the return loss of about 20 dB, and

A waveguide iris bandpass filter is designed in this paper. The proposed filter is created inside the structure by cutting inductive symmetrical windows known as irises. Later, using substrate integrated technology, its equivalent bandpass filter is released.

Two wideband bandpass filter (BPF) are proposed and designed using the U-slotted substrate integrated waveguide (SIW) cavities. The U-shape slots, etched on the SIW cavity, are used to form up a new multiple-mode resonator (MMR) in order to achieve a wide passband of operation while keeping the overall size of the filter circuit to be much compact.
