CIRCULAR POLARIZATION ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide a circular polarization antenna capable of receiving a circularly polarized wave by means of a configuration of combining one monopole antenna with a wire-shaped conductor orthogonal thereto and providing a power transfer part between them. SOLUTION: The circular polarization antenna 10 comprises: the monopole antenna 5 formed on a transparent dielectric film 8 and having a power feed terminal and an opening terminal; and a non-powered element 7 having a length component in the vertical direction with respect to an antenna shaft of the monopole antenna 5 and acting like the wire-shaped conductor not electrically connected to the monopole antenna 5. The non-powered element 7 is provided with the power transfer part capable of transmitting / receiving power to / from the monopole antenna 5 and arranged close to the opening terminal of the monopole antenna 5. The power transfer part is configured by folding at least either of the opening terminal of the monopole antenna 5 and one end of the non-powered element 7 and arranging the folded part nearly in parallel.
