ABSTRACT:
In an information transmitting system for radio-transmitting information between a fixed station and a mobile station moved within a predetermined moving range, an antenna apparatus is provided on the fixed station side. The antenna apparatus includes a large number of unit antennas, each of which functions as an antenna. These unit antennas are mutually connected to each other, and are arranged along the moving range of the mobile station. The information is transmitted/received in a radio transmission mode between the mobile station and the fixed station via an antenna of the fixed station and the antenna apparatus.
