Abstract

PURPOSE:To eliminate the breakage of an antenna, by constituting plural microstrip antennas by means of a dielectric substrate and attaching these antennas on the surface of a housing of a radio device. CONSTITUTION:Two microstrip antennas 9 are attached on the surface of a housing 10 of a radio device. For instance, one of these antennas can be used for an antenna for both transmission and reception, and the other one is used only for reception. A microstrip antenna has a flat structure and also can be miniaturized to be formed into a body with a housing of a radio device. In such constitution, an antenna protrusion can be eliminated to avoid the breakage of an antenna.
