UNIFIED ANTENNA FOR VEHICLE

摘要

PURPOSE: An integrated antenna for a vehicle is provided to complexly receive a multiband signal by displacing the amplitude of a current delivered to a feeding unit through ground. CONSTITUTION: Bottom housing is arranged on the upper side of a pad. A main printed circuit board is settled in the bottom housing. Top housing is connected to the pad and covers the main printed circuit board and the bottom housing. A first antenna unit(10) is formed into a helical antenna structure. A helical antenna forms a plurality of coils. A feeding unit(20) receives a received signal of the first antenna unit. A ground unit(30) is arranged in around the feeding unit. The ground unit displaces the amplitude of a current delivered to the feeding unit and receives frequency of multiband.
