Abstract (en)
A vehicular antenna apparatus includes a window glass (23) attached to a vehicle, a glass antenna (100) including a first antenna conductor, and a first feeding section (16) and a second feeding section (17) serving as a pair of feeding points of the first antenna conductor, a coaxial cable (70) including an inner conductor (71) connected to the first feeding section (16) and an outer conductor (72) is connected to the second feeding section (17), and a grounding member (73,75) configured to ground to a vehicle body a middle part (74) of the outer conductor (72) of the coaxial cable (70) extending from the pair of feeding points (16,17) to a signal processing unit (80) installed on the vehicle body. The first antenna conductor includes a first element (1A) connected to the first feeding section (16) and extending in a horizontal direction or a vertical direction. An inclination angle of the window glass (23) relative to a horizontal plane at a position of the pair of feeding points is greater than or equal to 10° and smaller than or equal to 30°. Even for such low inclination angles the vehicular antenna apparatus provides an antenna gain sufficient for receiving vertically polarized radio waves.
