Abstract

1510755 Automatic impedance matching HATFIELD INSTRUMENTS Ltd 2 July 1976 27736/76 Heading G3R [Also in Division H4] A control system which produces automatically a required closeness of impedance matching between a transmitter 1 and an antenna 2 includes a matching network 3, 4 a VSWR detector 7 giving an output signal representing the closeness of matching afforded by the network, respective electric motors 5, 6, for adjusting an inductor 3 and a capacitor 4 of the network, and units 8-17 responsive to a detector signal representative of less than a predetermined degree of matching to energize the motor 5 associated with the inductor to maximize the matching obtainable by adjustment of the inductor and thereafter to energize the motor 6 associated with the capacitor to maximize the matching. Circuit details of units 8-17 are given Figs. 2 and 3, (not shown).
