Abstract
The invention relates to an antenna structure for transmitting and/or receiving wavelengths of metric frequency or decimetric frequency, characterised in that it comprises n collinear antennas, each antenna comprising a radiating portion comprising a first succession of i coaxial radiating elements about a first axis alternating with at least an additional succession of i radiating elements about another axis, each antenna being independently powered by a coaxial cable, each antenna comprising at least one lower quarter-wave trap and at least one upper quarter-wave trap, at least a first antenna comprising at least one hollow core being configured to receive a coaxial cable intended for powering of another antenna collinear with the first antenna, at least one intermediate quarter-wave trap being arranged between two consecutive collinear antennas around a coaxial cable, and a terminal element.
