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...

A novel highly efficient leaky-wave antenna (LWA), based on a periodic set of holes created in half-mode substrate integrated waveguide (SIW), is conceived for automotive radar. The computer-aided design this partially filled SIW (PFSIW) LWA carried out using full-wave electromagnetic simulator. As proof-of-concept, an prototype having plate size 15 × 126 mm <sup xmlns:mml="http://www.w3.org/19...

in this paper a new low profile substrate integrated waveguide (siw) probe-fed h-plane horn antenna structure with improved gain is proposed. the proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...

A highly compact substrate integrated waveguide (SIW) self-diplexing antenna, operating at wireless local area network bands (3.6 and 5.4 GHz), is proposed in this letter. The antenna consists of two closely placed (0.022? g , where ? the guided wavelength 3.6 GHz) quarter-mode SIW resonators, e...

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
