It is the external view which showed the external appearance of the antenna apparatus for vehicles shown in FIG. FIG. 3 is an enlarged view of an amplifier portion of the vehicle antenna device shown in FIG. 2.

  Hereinafter, the best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described with reference to the drawings.

  First, the operation of attaching the quarter window 12 integrated with the vehicle antenna device 20 to the vehicle will be outlined. FIG. 1 shows an operation of attaching a quarter window 12, which is a small window at the rear of the vehicle, from the outside of the vehicle 10. The window frame portion of the vehicle 10 is provided with three locking claw holes that are fitted and locked with the vehicle locking claw provided on the back surface of the quarter window 12. As an attaching operation, a cable extending from the amplifier 16 of the vehicle antenna device 20 is passed through the window frame portion of the vehicle 10, and then the quarter window 12 is bonded to the vehicle locking claws and the quarter window edge. It fixes to the window frame part of the vehicle 10 with an agent. After the adhesive has hardened, connect the cable and attach the interior trim. Next, the vehicle antenna device 20 will be described in detail.

  FIG. 2 shows an appearance of the vehicle antenna device 20 shown in FIG. 1. From the antenna element 21 printed on the quarter window 12, the amplifier 16 disposed at the feeding point of the antenna element, and the amplifier 16. A cable 18 that extends and a conductive rubber 23 that connects the antenna element 21 and the amplifier 16 are provided. The quarter window 12 has a transparent window 19 and a window frame 15. The window frame 15 has three vehicle locking claws 14 for fixing to the vehicle, and an amplifier for fixing the amplifier to the quarter window 12. And four locking claws 17 for the amplifier.

  The quarter window 12 according to the present embodiment is the same as the window frame and the three latching claws formed on the window frame by resin molding the transparent window first after the resin molding of the transparent window. And four pin-shaped locking claws for fixing the amplifier formed on the window frame. The antenna element was printed with conductive ink after the quarter window 12 was molded. Next, a method for connecting the antenna element and the amplifier will be described.

  FIG. 3 is an enlarged view of the vehicle antenna device 20 shown in FIG. 2 and shows a connection portion between the antenna element 21 and the amplifier 16.
