Abstract
A GPS antenna is provided with a reflective conductor portion. Thereby, an electromagnetic wave radiated from an antenna conductor portion in a predetermined direction can be grounded electrically, and thus radiation of the electromagnetic wave in a direction (arbitrary direction) opposite to the predetermined direction can be enhanced. As a result, the directivity of the electromagnetic wave in the arbitrary direction can be enhanced to improve the positioning accuracy.
