In this paper, the research advances in silicon based millimeter wave and THz ICs in the State Key Laboratory of Millimeter Waves is reviewed, which consists of millimeter wave amplifiers, mixers, oscillators at Q, V and W and D band based on CMOS technology, and several research approaches of THz passive ICs including cavity and filter structures using SIW-like (Substrate Integrated Waveguide-...

This paper presents a technique for the efficient and accurate determination of resonant frequencies and quality factors of Substrate Integrated Waveguide (SIW) resonators. To consider resonators of a general shape the SIW structure is modelled as a parallel plate waveguide populated with metalized via holes. The field into the SIW cavity is found by solving the scattering problem for the set o...

Received Nov 9, 2017 Revised Jan 12, 2018 Accepted Feb 23, 2018 In this paper, design characteristics of cross slot coupling have been explored and realized in a proposed dual-layer SIW prototype for bandwidth enhancement at 10.0 GHz. The assembled prototype consists of two SMAmicrostrip input/output interface with low-loss microstrip-taper via transition and two manually stacked SIW structures...

Fluorescent microtubes based on α-Keggin tungstosilicate and fluorescein (SiW(12)-F) have been obtained by using a simple method, which present tunable photoluminescence from sky blue to green to red by variation of excitation light. The SiW(12) component can inhibit photobleaching of fluorescein.

Wave propagation in single layer substrate integrated waveguides (SIWs) loaded by embedded split ring resonators (ESRRs) is discussed theoretically and experimentally. It is shown that the loaded SIW can support a backward-wave passband below the cutoff frequency (fc) of the host SIW or a stopband will appear above fc if the effective transversal permeability is negative. In addition, varactor-...

A low cost 4  4 butler matrix fed antenna array has been proposed for Ku band applications. At high frequencies, the ohmic and dielectric losses are high and also the undesired feed radiation is more in the case of microstrip line feed, therefore substrate integrated waveguide (SIW) has been used to feed the antenna elements. The implementation of SIW technology improved the radiation performa...

This paper presents an overview of substrate integrated waveguide (SIW) design activities at the University of Victoria. Mode-matching techniques (MMTs) are employed to facilitate the design of planar SIW circuits as well as surface mounted waveguide (SMW) components. Active component integration and antenna design employ commercially available field solvers. Each category is highlighted by a s...
