FIELD: physics, radio.
SUBSTANCE: invention is related to antenna engineering and may be used in communication systems of decimetre and centimetre ranges of waves, in particular as wideband combined antenna of cellular communication, and also in radio homing and non-linear radiolocation. Antenna comprises row of symmetrical vibrators, twin-lead distribution line excited by coaxial feeder, at that every further symmetric vibrator in row is energised as antiphased to previous symmetric vibrator, and ratio of neighboring vibrator arms lengths and ratio of distances between symmetrical vibrators are selected by ratios of optimal log-periodic structure creation. Symmetric vibrators and twin-lead distribution line are arranged in the form of strip conductors installed on both sides of dielectric base.
EFFECT: reduced coefficient of stationary wave in coaxial feeder in wide band of frequencies with overlap factor of at least 2.
