COMPACT BROADBAND THREE-COMPONENT RECEIVING ANTENNA DEVICE Russian patent published in 2016 - IPC H01Q7/00 

FIELD: radio engineering, communication.

SUBSTANCE: three-component receiving antenna device comprises a metal base on which there are two mutually orthogonal receiving magnetic antennae on rod-shaped ferrite cores with windings at each of the cores, three balancing transformers, three sockets, a capacitive antenna and antenna reduction end elements. Differential winding leads are connected through the balancing transformers to corresponding sockets. Electric shields of the antennae have longitudinal slits, communication lines are shielded, magnetic antennae are vertically offset relative to each other and are placed over the metal base, the plane of which is parallel to the longitudinal axes of the magnetic antennae, and the windings of each magnetic antenna are placed in their own electric shield. The capacitive antenna comprises upper and lower metallic electrodes consisting of four flat segments which are arranged axially symmetrical in one plane around the central axis of the device and are electrically connected to each other at a common point. The plane of the upper electrode is situated over the upper magnetic antenna, and the plane of the lower electrode is situated below the lower magnetic antenna.

EFFECT: eliminating ambiguity of bearing measurement.
