Recent mobility technology has rapidly developed with intelligent, useful applications. From real-time communications to object-detection and sensing, the wireless is applied to make the advancement of mobility facilities using RF and microwave technology. The microwave and RF circuits requires the compact, planar, and light-weight designs, while the system should be fast and multi-functional. The automotive needs to sense object and distance from the others. This special session covers the various advanced RF and microwave technologies including circuit and system design theory, new material applications, and practical implementations.
