Design and Experimental Validation of a 12 GHz High-Gain 4 × 4 Patch Antenna Array for $S_{21}$ Phase-Based Vital Signs Monitoring

Sensors
Non-contact monitoring of human vital signs using microwave radar has attracted increasing attention due to its capability to operate unobtrusively and through clothing or light obstacles. In vector network analyzer (VNA)-based radar systems, vital signs

Intelligent vehicle scheduling in open-pit mines based on 5G antenna and improved Dijkstra algorithm

Gong-kuang zidonghua
Complex terrains such as deep pits and high slopes in open-pit mines cause physical signal blockage and multipath fading. Furthermore, existing path-planning algorithms tend to result in unstable vehicle trajectories or congestion due to local optima ...

Status of the design of a Wide Band beam Current Monitor (WBCM) for EUROTeV [PDF]

, 2006
In the framework of EUROTeV, the conceptual design of a new wide band wall current monitor is being carried out. The design is based on the wall current monitors presently installed in CTF3. The new design aims to increase the bandwidth up to 20 GHz. The
