TRANSCEIVING ANTENNA OF LOOP TYPE Russian patent published in 2019 - IPC H01Q7/00 

FIELD: antenna equipment.

SUBSTANCE: invention can be used for development of communication systems using an antenna near-field zone. Essence of invention consists in the fact that multiturn transceiving antenna contains two open conducting loops and two capacitors of variable capacitance, as opened conductive loops there used are coils, and third coil is introduced, wherein all three coils are wound on one frame, and two switches, and all antenna elements are placed on one protective screened frame, first contact of transmitting coil is connected to first output of transmitter, second contact of transmitting coil is connected in series to first contact of first contour capacitor of variable capacitance, second contact of which is connected to second output of transmitter, first contact of first switch is connected to first contact of first receiving coil, second contact of which is connected to third contact of second switch, second contact of which is connected to second contact of first switch, third contact of which is connected to first input of receiver and first contact of second contour capacitor of variable capacitance, second contact of which is connected to second input of receiver and second input of second receiving coil, second input of which is connected to third contact of second switch.

EFFECT: enabling development of communication systems using the near-field antenna field.
