Title: Waveguide-based MEMS tunable filters and phase shifters
Usefulness: Waveguide-based MEMS tunable filters and phase shifters
Summary: Tunable iris filter such as micro electro mechanical system (MEMS) tunable filter for use as phase shifter (claimed) in millimeter wave system in security and sensing system e.g. weather monitoring system, radar system, automobile crush avoidance system, airplane landing guidance system. Also suits for multi-channel communication system, wireless and microwave application and electrically scanned antenna in vehicle.
Novelty: Tunable iris filter for millimeter wave system in e.g. weather monitoring system, has deformable membranes whose movement changes geometry of iris filter cavities to change frequency of signal to be filtered by filter
