Abstract

A waveguide arrangement having a longitudinal extension, along which an electromagnetic wave may propagate, and comprising at least one waveguide part and a feeding arrangement which is arranged for feeding said waveguide part with a first polarization and a second polarization, said polarizations being mutually orthogonal. The feeding arrangement comprises a dielectric carrier material comprising a first feeding conductor, feeding the first polarization and a second feeding conductor, feeding the second polarization, where the first polarization is excited by means of first excitation means fed by said first feeding conductor and the second polarization is excited by means of second excitation means fed by said second feeding conductor, where at least one excitation means is a symmetrical structure with respect to the longitudinal extension.
