VEHICLE ANTENNA DEVICE

摘要

A vehicle antenna device arranged in a door handle (1) includes a first antenna (11) which transmits and receives a communication radio wave to/from a key radio mobile device; and a second antenna (12) which transmits and receives a communication radio wave to/from a card radio mobile device. The second antenna (12) has a different frequency band of the transmission/reception radio wave from the first antenna (11). The first antenna (11) and the second antenna (12) generate magnetic fields whose directions are substantially orthogonal.
