PROBLEM TO BE SOLVED: To provide an antenna device whose angle can be freely adjusted so that the sensitivity of an antenna element may be optimal. SOLUTION: The antenna device is provided with the antenna element, an antenna unit which has a bottom cover and a top cover for the antenna element, and an antenna base to be fixed to an arbitrary installation surface. The antenna unit and the antenna base are coupled by an angle adjusting mechanism which uses a sliding bearing and has the function of free stop. The relative angle between the antenna unit and the antenna base can be freely adjusted. COPYRIGHT: (C)2005,JPO&NCIPI
