Abstract: A Yagi-Uda monopolar antenna configured to be mounted on the conductive surface of a vehicle, especially an aircraft. The antenna comprises: a radiating element, taking the form of a conductive plate, for example one having the shape of a disc, which plate is equipped with a return conductor; a reflecting element; and at least one directing element taking the form of a monopole that is folded on itself. The various elements are mounted on a substantially planar surface such as the skin of the fuselage of an aircraft. The antenna simultaneously has a wide operating band, a good compactness and a good directivity. It may especially serve as joint antenna for a plurality of air-ground communication systems of an aircraft.

Abstract: An antenna system for an aircraft, comprising one or more antennas configured and arranged on the aircraft to provide a downlink rate of at least one Gbps, the one or more antennas permitting a base cell tower placement with a diameter of at least 60 km, the one or more antennas being configured and arranged to support multiple data streams simultaneously, the one or more antennas supporting multiple polarizations, the one or more antennas having a high gain over most of a hemisphere around the one or more antennas of −85°≤θ≤85°, 0°≤φ≤360°.
