Vehicle antenna device

A vehicle antenna device comprising:

• a dielectric substrate having a first main surface and a second main surface;
• and
• a conductive film provided on a side of the second main surface and having an area of 0.025 m2 or more in a plan view of the dielectric substrate, the conductive film functioning as an AM antenna, wherein
• the conductive film has a sheet resistance value of 1.5×103Ω/□ or lower,
• AM broadcast band are receivable from a feeding point electrically connected to the conductive film,
• the feeding point electrically connected to the conductive film is a first feeding point,
• the vehicle antenna device includes:
• an antenna provided on a side of the first main surface and receiving radio waves of at least one of frequencies of a VHF band and a UHF band;
• an antenna electrode disposed inside an outer edge of a void area provided inside the conductive film in a plan view of the dielectric substrate;
• an antenna conductor connected to the antenna and disposed on the side of the first main surface;
• and
• a filter allowing a signal in a frequency band of radio waves of at least one of frequencies of the VHF band and the UHF band to pass and blocking a signal in a frequency band of AM broadcast band between the conductive film and a ground conductor, wherein
• the antenna conductor is electrically connected to the antenna electrode, and
• radio waves of at least one of frequencies of the VHF band and the UHF band are receivable by a signal received using the antenna electrode as a second feeding point.
