Abstract:
A synthesizer radiating system, wherein energy is transferred back and forth between an inductive antenna element and storage capacitance by controlled activation of switching circuits, comprising:a loop antenna element configured as a plurality of successive loop segments; a plurality of switch modules each coupled to a different pair of loop segments, each switch module including switch devices arranged for controlled activation to transfer energy back and forth between the storage capacitance and the loop segments coupled to the switch module; a control signal feed including at least one optical signal path coupled to each said switch module for control of activation of said switch devices; and a DC supply including a first DC coupling to a loop segment, DC couplings between successive loop segments, and DC couplings between loop segments and selected switch modules, said DC couplings arranged to enable coupling of a DC voltage to the switch modules via the loop segments, while limiting coupling of non-DC signals.
