MULTIPLE-TUNED SMALL HIGH-TEMPERATURE SUPERCONDUCTING ANTENNA Russian patent published in 2009 - IPC H01Q1/38 

FIELD: physics, radio.

SUBSTANCE: multiple-tuned small high-temperature superconducting antenna is related to radio engineering and may be used for operation in short- and ultrashort-wave ranges. Antenna comprises the first and second parallel dielectric plates, on surface of which flat spiral conductors are applied, being inverted to each other with direction of twisting opposite to each other, as well as capacitance platforms, which are connected accordingly with ends of flat spiral conductors, the third and fourth dielectric plates, on one of which flat symmetric vibrator and inlet flat loop are installed, and on the other one - outlet flat loop. Additional capacitance platforms may be connected to arms of flat symmetric vibrator, and low-noise amplifier - to outlet flat loop. Dielectric plates are installed with the possibility of variation of their mutual position. Flat spiral conductors, all capacitance platforms, inlet and outlet flat loops and flat symmetric vibrator are made of high-temperature superconductor.

EFFECT: increased efficiency factor of antenna with working band of frequencies matched with band of received signal.
