Low profile radiator for high gain aerials, free of floating potentials. The radiator is formed of a resonant cavity in the shape of a circular cylindrical crown open to the outer surface. This cavity is achieved by means of a metal disc above a ground plane, separated from one another by...
conjunction with analogue to digital converters AH 1 -AH y and subsequent division circuits D 1 -D y which divide the pair of signals of the initially fed-in high frequency voltages with the corresponding control signals, thereby obtaining outputs independent of the gain and phase shift in each...
