Abstract
A microwave system for locating a mobile element comprises a hollow tube forming a waveguide fed with microwave signals. A location beacon radiates into free space an electromagnetic wave derived from the microwave signals propagating in the waveguide. A location antenna attached to the mobile element receives the electromagnetic wave radiated by the beacon. The location beacon transmits to the antenna a single electric field signal enabling transmission of a location message.
