A novel air-filled E-plane rectangular waveguide (RWG) to substrate integrated waveguide (SIW) transition, which is suitable for Ka-band large-scale antenna arrays, is presented. The power is coupled between the RWG and SIW through two slots: one etched on the SIW ground plane and the other cut through metallic RWG narrow side wall (E-plane). A back-to-back transition is designed, fabricated, assembled,...
In this paper, a SIW quadrature hybrid (-3 dB branch[3] line coupler) is presented and designed for millimeterwave applications. Furthermore, a simple circuit model is proposed for fast design optimization of the presented junction. Simulated S-parameters results using both the proposed circuit model and HFSS package are provided for verification of the proposed model.
In this paper the design and manufacturing of a novel waveguide slot array antenna with two layers of substrate integrated waveguides is presented. This antenna which operates at 60 GHz is very compact and is suitable for a variety of 60 GHz applications which have become a hot topic recently. The feed waveguide runs underneath the main substrate layer containing the slot array and is coupled to the...
A simple, low cost novel series feeding scheme to rectangular dielectric resonator antenna linear array (RDRA) is proposed at millimeter wave frequency range. The coupling to resonator is achieved through narrow slots cut on the substrate integrated waveguide (SIW) broad wall excited by the waveguide dominant mode.
