Longitudinal slots on substrate integrated waveguide

A novel two-layer slot array antenna based on substrate integrated waveguide (SIW) technology was designed and simulated. Unlike already reported SIW slot arrays, the present design achieves considerable reduction in size by using a feed waveguide placed underneath the slot array and coupled through slanted slots to branches of the array.

This thesis presents novel traveling wave conformal shunt slot arrays on cylindrical substrate integrated waveguide (CSIW) placed on a cylindrical surface in the circumferential direction at K-band. Mutual couplings of longitudinal slots on broad wall of CSIW are formulated and active admittance formulas of the slots are derived

Design of radome-covered substrate integrated waveguide ... A design of a radome-covered slot antenna array based on Substrate Integrated Waveguide (SIW) technology is presented in this paper. The design method consists of the analysis of an isolated radiating element, the synthesis of a linear array, the optimization of a planar array, and the development of a power divider with a transition from a feeding metal waveguide to an SIW.

The scanning angle is three times in SIW compared to the hollow waveguide. In Cao et al. planar beam scanning substrate integrated waveguide (SIW) slot leaky-wave antenna (LWA) is proposed for enhancing scanning range and gain flatness using a modified composite right/left-handed transmission line (CRLH TL) structure. SIW slot antennas utilized for 60-GHz channel In this work, substrate integrated waveguide (SIW) slot antennas are proposed for 60-GHz channel characterization. The antennas consist of a group of three longitudinal slots placed in one or both broad walls of an SIW. Depending on the placement of the slot group, the SIW slot antenna achieves a directional or omnidirectional radiation pattern. Current and Future Research Trends in Substrate Integrated [9]. SIW are integrated waveguide-like structures fabri-cated by using two periodic rows of metallic vias or slots connecting the top and bottom ground planes of a dielectric substrate (Fig. 1). The SIW scheme belongs to the family of substrate integrated circuits that include other substrate integrated structures such as substrate integrated image A 460 GHz CMOS Substrate-Integrated-Waveguide Slot … UNIVERSITY OF CALGARY A 460 GHz CMOS Substrate-Integrated-Waveguide Slot Antenna by Hao Xie A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL
