Multiband Non-Invasive Microwave Sensor

This monograph focuses on the design, implementation and characterization of a concurrent dual band RF sensor for non-invasive detection of human vital signs. Exclusive title on multiband short range sensors and their biomedical applications, offers detailed analysis of subsystems based on fabricated and measured prototypes and verifies and discusses the system in the real-time environment. Discusses the practical difficulties of the design process and offers case studies based on the design.
