Zusammenfassung:An antenna (100) for an RFID reading apparatus having a plurality of single antennas (10) of the inverted-F type, wherein the single antennas (10) are arranged in a plane and are arranged tilted with respect to one another within the plane, and having a feed circuit (16) that is connected to the single antennas (10) to control the single antennas (10) to generate a circular polarization having a mutual phase offset corresponding to the tilt is provided. The antenna (100) in this respect has at least four single antennas (10a-d), the single antennas (10a-d) are arranged in a direction of rotation, and the antenna (100) has a common ground plane (20, 28) in parallel with the plane.
