ANTENNA DEVICE Russian patent published in 2015 - IPC H01Q13/08 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to an antenna device. The antenna device includes an antenna element and a substrate unit, wherein the antenna element includes an antenna base, a radiating electrode, first and second power supply elements and a ground electrode. The substrate unit includes a distribution circuit unit C1 and a phase-shifting circuit unit C2, wherein the distribution circuit unit C1 includes a connecting element 321, channel elements 322A, 322B having a channel length of 1/4λ, and a resistor 323, and the phase-shifting circuit unit C2 includes a channel element 324A to a first power supply element and a channel element 324B to a second power supply element which, is longer than the channel element 324A by 1/4 λ. The phase-shifting circuit unit C2 and the distribution circuit unit C1 are on the same surface of the substrate unit. The phase-shifting circuit unit C2 is located within the channel elements 322A, 322B of the distribution circuit unit C1.

EFFECT: enabling reception of signals in two frequency bands.
