FIELD: antennas for mobile communication systems. SUBSTANCE: antenna has orthogonally wound spiral conductors. First spiral conductor is wound in one direction relative to vertical axis V of antenna. Second spiral conductor is wound in other direction relative to vertical axis V. In one of antenna versions spiral conductors are different in length for respective first and second frequency bands. In addition, first and second spiral conductors are wound so that they are orthogonal to one another in horizontal plane where they are intersecting or horizontally spaced apart through minimal distance. EFFECT: reduced crosstalk probability, provision for using separate antennas in close proximity to each other. 16 cl, 9 dwg
