Abstract (en)
A vehicle-mount antenna device is provided in which stable antenna characteristics can be obtained with an influence of common mode noise being reduced. A vehicle -mount antenna device 200 is configured with an antenna unit 210 and a connector-equipped coaxial cable 120 being connected to each other. The antenna unit 210 includes a feeding element 111 and a parasitic element 112, with the feeding element 111 being connected to a + input of an amplifier circuit 113 and the parasitic element 112 being connected to a ground plane 115 of the amplifier circuit 113. An output from the amplifier circuit 113 is connected to a center conductor 121 of the coaxial cable 120 via a filter 216, and the ground plane 115 is connected to an outer conductor 122 of the coaxial cable also via the filter 216.
