A novel design methodology is presented to co-optimise an active receiver antenna, combining a planar rectangular ring antenna and a low noise amplifier, operating from 2.4 to 2.485 GHz. A Doppler radar experiment based on this active antenna illustrates the excellent noise performance resulting from this approach.
