Summary:A conductive micro-strip line, a feeding line in contact with the micro-strip, and a radiation element connected to the feeding line are provided on a dielectric or semiconductor substrate, and a ground conductor is provided on the side of the substrate opposite to the micro-strip line to establish a diversification antenna and an array antenna. In accordance with another aspect, a plurality of antennas, each comprising a dielectric or semiconductor substrate, a conductive film provided on one side of the substrate for constituting a radiation element and a micro-strip line including a feeding line leading to the radiation element, and a ground conductor film provided on the other side of the substrate, are arranged. A coaxial feeding line leading to one of the antennas is provided along the ground plane, of another antenna, on which the ground conductor film is provided. This construction inhibits the influence of the coaxial feeding line on the radiation and impedance characteristics of another antenna.
