Baolin Cao, Hao Wang and Yong Huang - NSFC microstrip-based ridge gap waveguide (GWG) technology is applied to feed the SIC subarrays. Furthermore, for measurement purposes, a wideband transition structure between rectangular waveguide (RWG) and GWG is designed. Measured results show that an 8×8 slot array with the transition achieves a maximum Chalmers Publication Library Chalmers Publication Library 2×2-slot Element for 60GHz Planar Array Antenna Realized on Two Doubled-sided PCBs Using SIW Cavity and EBG-type Soft Surface fed by Microstrip-Ridge Gap Waveguide This document has been downloaded from Chalmers Publication Library (CPL).

Abstract: This paper presents an 8 × 8-element slot array antenna with single-layered corporate-feed based on the ridge gap waveguide (RGW) technology in the 60 GHz band. As is well known, a corporate-feed slot array antenna usually has backed cavities to increase the bandwidth and provides a space for its distribution network, and therefore three layers in total: one layer for radiating ... Corporate distribution networks for slot array antenna ... gap waveguide technology has a large potential for millimeter wave applications. To date, some array antennas have been realized based on gap waveguide distribution networks: a 4x1 slot array fed by ridge gap waveguide [7], a 4×4 horn array at 15 GHz fed by inverted microstrip gap waveguide in [8], and a 4×4 slot array Planar slot‐array antenna fed by an oversized quasi‐TEM ... We propose a novel planar slot‐array antenna fed by a new guiding structure which forces a quasi‐TEM mode within an oversized rectangular waveguide. To achieve a quasi‐TEM mode throughout the waveguide a hard surface is placed on the bottom surface of the waveguide while the radiating slots are at the upper face.

Slot Antennas

A novel fully on-chip antenna based on a metasurface fabricated in a 180-nm BiCMOS process is presented. Inspired by the concept of high impedance surface (HIS), this metasurface is not used as a reflector below an antenna as commonly done. Instead, it is used as a radiator by itself. An antenna design in gap waveguide using CST - Semantic Scholar These papers present the propose of a double layer slot array antenna at microwave frequency range K-band in gap waveguide technology. Gap waveguide technology is a solution to reduce the performance gap between planar transmission lines and metal waveguide in terms of loss, manufacturing flexibility and cost.
