Substrate Integrated Waveguide (SIW) technology is the most promising candidate for the implementation of millimeter-wave (mm-wave) integrated circuits and systems for the next decade. Based on planar dielectric substrates with top and bottom metal layers perforated with metalized holes, SIW structures offer a compact, low loss, flexible, and cost-effective(More)
— The additive manufacturing technique of 3D printing has become increasingly popular for designs that have been previously unachievable due to cost and design complexity. Due to the special mechanical properties of NinjaFlex [1], there is great potential for its use in the 3D printed fabrications of numerous RF applications, such as strain sensors and(More)
The implementation of fully three-dimensional (3D) substrate integrated waveguide (SIW) components by using an additive manufacturing technique is demonstrated for the first time. In particular, a 3D printing process based on the t-glase filament has been adopted. 3D printing allows for the manufacturing of very complex shapes in a few hours, thus leading(More)
—This paper presents a novel algorithm for the analysis of quasi-optical filters, consisting of thick metal screens perforated periodically with arbitrarily shaped apertures. The algorithm is based on the widely used method of moments (MoM) in conjunction with entire domain basis functions. Its flexibility, accuracy, and rapidity depend on the use of the(More)
