Abstract
Output signals from a set of Faraday loops located in a common plane are combined selectively to simulate the output signals from a set of mutually orthogonal antennas. This arrangement and use of Faraday loops are especially suitable in a hospital environment for monitoring patients. Because of the availability of output signals from a set of equivalent orthogonal antennas, any danger of a gap in the monitoring of the patient is greatly minimized; the patient can be monitored regardless of the changing orientation of the patient with regards to the monitoring antennas.
