Key features for these are, single-layer and mass producible, high efficiency and high gain. State-of-the-art design/analysis techniques for novel structures as well as the characteristics in millimeter-wave band are reviewed. Beam switching, connectors to RF circuits and the use of PCB substrate are mentioned on demands from systems. The latest application in the systems is demonstrated, such as FWA, LAN and TV-video link etc.
