V-slot antenna for circular polarization

Abstract

The present invention relates to a circular polarized antenna 0comprising a planar dielectric substrate (1) comprising a front (5) and a back (6) dielectric face, at least one subantenna means comprising a first (2) and second (3) element for radiating and receiving circular polarized electromagnetic signals, at least one transmission line means (4) for transmitting signals from and to said at least one subantenna means, wherein the antenna is characterized in that the first and second elements (2, 3) of the subantenna means are slots arranged orthogonal to each other in a V-shape on the front dielectric face (5) of the substrate (1) and in that the transmission line means (4) are arranged on the back dielectric face (6) of the substrate (1). This structure provides a simple configuration which can be produced at low costs and is suitable for the use in a planar array antenna, in particular due to the decoupling of the feed system from the radiating element.
