TL;DR: In this article, a substrate integrated folded waveguide (SIFW), integrated transition to shielded stripline and a SIFW filter are demonstrated and shown to be in good agreement with X band measurements.
Abstract: A substrate integrated folded waveguide (SIFW), integrated transition to shielded stripline and a SIFW filter are demonstrated and shown to be in good agreement with X band measurements. Both the filter and waveguide are considerably smaller than their unfolded counterparts. Furthermore, the filter response is defined purely in terms of a photolithographically etched plane.

TL;DR: In this paper, the design and fabrication of substrate-integrated waveguides and filters for use at millimeter-wave frequencies is presented. Butts et al. used photo-imageable thick-film materials.
Abstract: This paper presents the design and fabrication of substrate-integrated waveguides and filters for use at millimeter-wave frequencies. The components described are fabricated using photoimageable thick-film materials. Measurements on V- and W-band waveguide-to-microstrip transitions are presented. Losses resulting from the reduced-height nature of the waveguides are extracted from thru-relect-line calibration standards illustrating the effect of current losses in the broadwalls of the waveguides. The design of fourth-order 0.01-dB ripple Chebyshev resonant cavity filters operating at V-, W-, D-, and G-band is presented. The measured results of all components are in excellent agreement with simulated predictions.

TL;DR: In this paper, a W-band substrate integrated waveguide slot antenna has been designed and tested using a reduced height waveguide in photo-imageable thick film technology, which is used for return loss and radiation pattern measurements.
Abstract: A W-band substrate integrated waveguide slot antenna has been designed and tested. The antenna has been realised using a reduced height waveguide in photoimageable thick film technology. Experimental and simulated return loss and radiation pattern measurements are presented.

TL;DR: In this article, a slot antenna in a folded substrate-integrated waveguide is shown, which has half the width of the other types of substrate integrated waveguide and allows arrays of slot antennas to be more highly integrated.
Abstract: We show a slot antenna in a folded substrate-integrated waveguide. These waveguides have half the width of the other types of substrate-integrated waveguide. As such the present structure allows arrays of slot antennas to be more highly integrated.

TL;DR: In this paper, a slot antenna using a C type substrate integrated waveguide is presented, which can be easily integrated with other microwave or millimetre wave devices, and it is shown that using the C type compact waveguide it is possible to produce a smaller waveguide slot antenna than the one in standard substrate Integrated Waveguide.

TL;DR: In this paper, the design and performance of 180 GHz substrate integrated waveguide filters is presented, where photo-imageable thick film technology can achieve the precise dimensional control needed for design at G-band.
Abstract: The design and performance of 180 GHz substrate integrated waveguide filters is presented. It is shown that photoimageable thick film technology can achieve the precise dimensional control needed for design at G-band. TRL calibration standards are fabricated in the substrate integrated waveguide medium itself and excellent results are obtained for the 140–200 GHz frequency range. 0.1 and 0.01dB ripple filters are designed and fabricated, with 8 and 6.2% relative bandwidths. The measured results show excellent agreement with electromagnetic simulations.

TL;DR: The surface of a borosilicate glass has been modified by an electrical ion depletion process with the aim of permanently removing sodium ions, thus, reducing its loss at microwave frequencies.
Abstract: The surface of a borosilicate glass has been modified by an electrical ion depletion process with the aim of permanently removing sodium ions, thus, reducing its loss at microwave frequencies. The modified layer has sufficient depth such that coplanar waveguides formed on top of the glass exhibit lower loss in comparison with waveguides formed on undepleted glass.

TL;DR: In this paper, a highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed, which is built using two substrates aligned with conducting vias.
Abstract: A highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed in this paper. The device has three key components: a non adiating SMA to standard waveguide transition, a power divider from standard waveguide to folded waveguides, and slot arrays on the folded waveguide. The antenna is built using two substrates aligned with conducting vias which makes the device, low profile, small size, low cost and easy to manufacture.
