Abstract (en)
[origin: EP0027067A1] 1. Plane two-wire aerial with transversal radiation comprising a first and second conducting line 1, 2 disposed facing each other on a first and a second parallel plane P1 and P2 respectively, characterized in that the first, respectively second, conducting line 1, 2 presents a plurality of N folds, delimiting the conducting elements that are each disposed opposite a conducting element of the other line, form respectively a pair with the opposite facing conducting elements and which are contained in a sector of the first, respectively second, plane limited respectively by two secant straight lines constituting the enclosure of the first, respectively second, conducting line 1, 2 and in that each conducting element of the second line 2 has an electric length that is longer than that of the conducting element of the first line 1 situated facing opposite and which is such that at least two conducting elements situated facing opposite and forming a pair are through-crossed by currents in phase and that the average length of the conducting elements of the said pair and an adjacent pair at least is equal to lambda/2, in which lambda is the wave length of maximal radiation.
