研究目的
To review the fundamentals of integrated substrate gap waveguide (ISGW) in structure and operation principle, and to demonstrate its advantages over substrate integrated waveguide (SIW) for 5G microwave and millimeter-wave components.
研究成果
ISGW offers better integration, self-packaging and additional design freedoms compared with SIW. It can be used for design of various passive microwave and millimeter-wave components, such antennas, couplers and filters, leading to better performance. ISGW is considered a highly potential technology for 5G wireless communications.
研究不足
The study primarily focuses on the advantages of ISGW over SIW and does not extensively discuss potential limitations or areas for optimization in the ISGW design.
