Vehicle antenna device

Abstract

To provide a vehicle antenna device which includes multiple antennas, the frequency bands of radio waves to be transmitted and received by the multiple antennas being at least partially different from each other, proximate to each other and which can reduce the degradation of the transmission/reception sensitivity of each of the multiple antennas. A vehicle antenna device to be mounted on a vehicle, comprising: a first antenna capable of transmitting and receiving radio waves of a first frequency band; and a second antenna proximate to the first antenna and capable of transmitting and receiving radio waves of a second frequency band including a frequency band higher than the first frequency band, wherein at least one of the first antenna and the second antenna is disposed in or on window glass of the vehicle or in the vicinity of the window glass, and wherein the second antenna includes a power supply unit to which a high-pass filter is connected.
