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. A 460 GHz CMOS Substrate-Integrated-Waveguide Slot Antenna 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 Leaky Wave Antennas Designed on a Substrate Integrated ...

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.

Substrate Integrated Waveguide (SIW) Leaky-Wave Antenna With ... A novel slotted substrate integrated waveguide (SIW) leaky-wave antenna is proposed. This antenna works in the TE mode of the SIW. Leakage is obtained by introducing a periodic set of transverse slots on the top of the SIW, which interrupt the current flow on the top wall.

A new technique for designing the Substrate Integrated Waveguide (SIW) frequency-agile slot antenna is presented in this paper. Similar to the metallic waveguide counterpart, the SIW is a uni-conductor guided-wave structure and inherently difficult in the electronically tunable applications.
