object: A GPS antenna unit for a two-wheeled motor vehicle capable of being mounted to the vehicle without impairing the appearance of the vehicle is to be provided. Solving Means: A GPS antenna unit for a two-wheeled motor vehicle, mounted to the two-wheeled motor vehicle to receive a radio wave from a GPS satellite includes a helical antenna(12)extending to the exterior from a unit case (11) and a controller (13) accommodated within the unit case(11) to process the radio wave received by the helical antenna(12). Since the projection area of the helical antenna is small, the GPS antenna can be mounted even to a two-wheeled motor vehicle having few planar portions facing the zenith, without impairing the appearance and aerodynamic characteristics of the vehicle. <IMAGE> |
