MEDIUM-WAVE BAND CAPACITIVE TRANSCEIVING ANTENNA Russian patent published in 2020 - IPC H01Q9/04 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering and can be used in making transceiving antenna devices of radio communication equipment of medium-wave band. According to the invention, the capacitance transceiving antenna of the medium-wave band comprises a capacitance element developed in space in the form of two flat current conducting surfaces located perpendicular to each other, as well as variable inductance coil and movable communication coil connected to capacitive element so that electrically there is formed tunable resonant oscillatory circuit (antenna circuit). Frequency tuning of the antenna is carried out by inserting into the coil a variable inductance of a ferromagnetic core made from amorphous iron. Adjustment of antenna matching with feeder line is performed by movable communication coil connected in series with variable inductance coil and located coaxially with it.

EFFECT: technical result of invention is significant reduction of weight and size characteristics of variable inductance coil, simplification of electromechanical drive of tuning of operating frequency of antenna circuit, as well as simplification of adjustment of its matching with feeder line.
