Abstract (en)

[origin: EP2256864A1] The antenna has a slot radiators provided with a longitudinal extension unit along a sectional line between a symmetric level and an electrical conducting base surface (2) with a slot radiator-connection location (7). The slot radiators and an electrical dipole radiator are connected with a dipole-feeder line (6) via a distributor network (13) with an antenna-connection point (12) according to the quantity and phase in a manner such that circular polarization is enabled in a distant field at a frequency, on which the slot and dipole radiators are coordinated with each other.
