Title:
VEHICLE-MOUNTED ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/079250
Kind Code:
A1
Abstract:
Provided is a vehicle-mounted antenna device with which a deterioration in the performance of an antenna can be adequately suppressed even if an electronic component is installed in the antenna device. A vehicle-mounted antenna device having an antenna 3 is provided with: an electronic component 7 which is electrically isolated from the antenna 3 and includes a connector 53 having an inner terminal 53a and an outer terminal 53b; a coaxial cable 61 one end of which is connected to the connector 53; and a shielding member 8 which is grounded to a vehicle body, which is an earth, and blocks at least a portion of noise generated by the electronic component 7 from reaching the antenna 3. The coaxial cable 61 includes an inner conductor connected to the inner terminal 53a and an outer conductor connected to the outer terminal 53b, and the electronic component 7 is electrically connected to the shielding member 8 via only the outer terminal 53b.
