Abstract

An improved eleven antenna is disclosed, comprising a conducting body acting as a ground plane; and at least one pair of log-periodic dipole arrays arranged above the ground plane, the dipoles of said pair of log-periodic arrays of dipoles forming dipole pairs of parallel and oppositely located dipoles of the same dimensions and arranged in such a way that the geometrical centres of each of said dipole pairs and their images in the ground plane are coinciding,wherein each dipole is a folded dipole comprising two or more parallel or nearly parallel conducting strips that are connected at one or more points or over an extended part of the conducting strips. Further, a plurality of the folded dipoles, within each of said log-periodic dipole array, being closer to said geometrical centre are extending in a first plane, and wherein the remaining at least one folded dipole being located most far away from said geometrical centre is arranged to extend in at least one additional plane, said additional plane(s) forming an angle relative to said first plane. Hereby,a more compact antenna is achieved.
