FIELD: antenna equipment.
SUBSTANCE: resonance frequency of the antenna is disturbed when the user's body part is approached or touched with the antenna and results in loss of efficiency. Antenna can be tuned by changing its full load capacitance so that the full antenna load capacity falls within the control capacitance range of said control capacitance, where the antenna can operate at a predetermined operating resonant frequency or nearby it. Tunable capacitor can be connected to an antenna for tuning the full capacitance of the antenna load.
EFFECT: providing boundaries for full capacity of antenna system, for which disconnection of capacitance caused by misaligned antenna is retained within permissible range.
