COMPACT BROADBAND FOUR-COMPONENT RECEIVING ANTENNA DEVICE Russian patent published in 2018 - IPC H01Q7/04 

FIELD: radio engineering.

SUBSTANCE: device relates to the radio-receiving equipment and can be used in radio direction finding, radio navigation and radio monitoring. Device, in addition to the known solution, comprises a fourth balanced transformer, a fourth connector, fourth shielded communication lines, receiving frame magnetic antenna, consisting of four flat identical sections of a multi-turn shielded coil with an annular slot in the shield of each flat section. Flat identical sections of a multi-turn shielded coil are located axially symmetrically in one plane around the central axis of the device. Each flat section of a multi-turn shielded coil is located above the corresponding flat segment of the upper metal electrode of the receiving electrical antenna. Turns of each section and all flat sections of the multi-turn shielded coil are successively electrically connected to each other, forming the winding of the receiving frame magnetic antenna. Receiving frame magnetic antenna is separated from the upper metal electrode of the receiving electrical antenna by a flat dielectric spacer with a central hole. Wires of the fourth shielded lines are connected to the winding of the receiving frame magnetic antenna, wires electrically connect this winding to the differential input of the fourth balanced transformer, output of which is electrically connected to the fourth connector. Fourth shielded communication lines are laid along the surface of the electric shield of the lower receiving magnetic antenna on the rod ferrite core, the end elements of the antenna drop and metal base are symmetrical with respect to the central section of the core of the lower receiving magnetic antenna, and the shielding casings of the fourth shielded communication lines are electrically connected to the electric shield of the multi-turn shielded coil of the receiving frame magnetic antenna, electric shield of the lower receiving magnetic antenna on the rod ferrite core, end elements of the antenna drop and metal base.

EFFECT: technical result is the possibility of bearing along the angle together with bearing along the azimuth angle to determine the location of elevated sources of electromagnetic radiation.
