FIELD: information technology.
SUBSTANCE: antenna-matching device, having a controlled matching circuit, whose input serves as the input of the antenna and the output as the input of a transceiver, additionally contains a communication circuit, a pulse generator, a counter, a control voltage accumulator and connection buses, wherein the input of the controlled matching circuit is connected to the input of the communication circuit, and the output of the communication circuit is connected to the resonator of the pulse generator, the output of the pulse generator is connected to the input of the counter, counter trigger outputs are connected by a bus to inputs of the control voltage accumulator, and outputs of the control voltage accumulator are connected by a bus to leads of the controlled matching circuit.
EFFECT: automatic adjustment of impedance which compensates for the mismatch caused by the hand or head of a person.
