Abstract
An on-vehicle film antenna is constructed with a loop antenna and a monopole antenna and attached to a vehicle windshield. The loop antenna has a first element set in length to correspond to a first radio wave of a first frequency band. One end of the first element is connected to a power supply near a border section between a vehicle chassis and the vehicle windshield, and the other end of the first element is connected to the vehicle chassis. The monopole antenna has a second element set in length to correspond to a second radio wave of a second frequency band. One end of the second element is connected to the power supply near the border section in common with the one end of the first element, and the other end of the second element is disconnected from the vehicle chassis.
