QUICKLY RECONFIGURABLE SHORT-WAVE CAPACITIVE TRANSCEIVING ANTENNA Russian patent published in 2021 - IPC H01Q9/04 

FIELD: antennas.

SUBSTANCE: invention relates to antenna technology and can be used in manufacture of transceiving antenna apparatuses for radio communication equipment in the HF frequency range. According to the invention, the quickly configurable short-wave capacitive transceiving antenna is comprised of a capacitive element deployed in space in form of two flat current-conducting surfaces located perpendicular to each other, as well as a variable inductance coil and a movable coupling coil connected with the capacitive element so as to electrically form a resonant oscillatory circuit configurable by frequency. The variable inductance coil provides smooth reconfiguration of the operating frequency of the capacitive antenna. The frequency hopping is provided by the additional current-conducting plates of different sizes installed in the capacitive element configured to be electrically connected to the lower horizontal current-conducting surface of the capacitive element according to a predetermined algorithm using a switching unit. The capacitance in the antenna circuit is therein changed by hopping, and the operating frequency of the antenna is changed accordingly. The value of the frequency jump will depend on the area of the additionally connected plates, and the number of discrete operating frequencies of the antenna configuration will be determined by the amount thereof.

EFFECT: technical result of the invention is the expanded operational capabilities of the capacitive transceiving antenna due to implementation of resonant frequency hopping of the antenna circuit therein.
