DIPOLE ANTENNA Russian patent published in 2012 - IPC H01Q9/28 

FIELD: radio engineering.

SUBSTANCE: antenna has a double-wire feed line and, lying at an angle to each other, a first 1, a second 2, a third 3 and a fourth 4 thin wires, wherein adjacent ends of the first 1 and third 3 wires, as well as the second 2 and fourth 4 wires are galvanically connected to each other and each of the leads 5 and 6 of the double-wire feed line 7. All wires are identical and have length which is equal to a quarter of the central wavelength of the operating frequency range. The interconnected wires 1 and 3, as well as 2 and 4 lie in mutually orthogonal planes, and the angle between connected wires is selected such that the power polynomial-based relationship is satisfied: R_A=73.0775-94.426532α'+846.861388α'²-3268.248784α'³+4151.07214α'⁴-1703.376622α'⁵, where R_A is the active input resistance which varies from 5 ohms to 73 ohms, α'=α/180, α is the angle between connected wires which varies from 0° to 180°.

EFFECT: enabling smooth adjustment of the antenna input resistance by changing the angle between connected wires.
