MULTI-BAND ANTENNA FOR VEHICLE

摘要

The present invention relates to a multi-band antenna for a vehicle. According to the present invention, the multi-band antenna for a vehicle installed on an upper surface of a main board positioned inside the multi-band antenna for the vehicle formed as a dome shape of a line type, wherein the main board includes a feeding circuit and a ground surface formed therein. By mutually coupling first and second helical radiators mutually separated by a predetermined distance provided in a first dual helical antenna formed on a printed circuit board (PCB) substrate on the upper surface of the main board positioned inside the multi-band antenna for a vehicle, the multi-band antenna for the vehicle can be operated in various broadcasting frequency band while satisfying an antenna property required for each frequency band.
