Substrate integrated nonradiative dielectric waveguide

Novel Empty Substrate Integrated Waveguide for High-Performance Microwave Integrated Circuits

“…Examples of these structures, generically known as Substrate Integrated Circuits (SIC), are the Substrate Integrated Slab Waveguide (SISW) [2], the Substrate Integrated Non-Radiating Dielectric (SINRD) guide [3], [4], which is based on the Nonradiative Dielectric Waveguide [5], or the Half Mode Substrate Integrated Waveguide (HMSIW) [6], among others. Of all of them, the SIW is the most popular, because it is quite straightforward to apply the well known design techniques of rectangular waveguides to this topology.…”

Sinrd Circuits Analysis With Wcip

“…The new manufacturing Substrate Integrated Circuits (SICs), have been proposed for the realization of NRD waveguide. This new technique, called SINRD, allows the integration of NRD waveguide on substrates [2,3]. The advantage of SINRD waveguide is its ability to be integrated on the same dielectric substrate as the SIW technology [4].…”

A Simplified Implementation of Substrate Integrated Non-Radiative Dielectric Waveguide at Millimeter-Wave Frequencies

“…On the other hand, the development of substrate integrated circuits (SICs) suggests that any planar and non-planar structures can be integrated in a hybrid or monolithic manner thanks to the synthesis of non-planar structures in planar form. Designing the NRD guide with the concept of SICs yields the substrate integrated NRD (SINRD) guide [5,6]. This differs from the NRD guide by the fact that the side regions that flank the guiding channel are made of a lower permittivity dielectric (other than air).…”
