PURPOSE:To elevate the nondirectional characteristic, by providing the start point of an antenna for very high frequency so that it is shifted from the longitudinal center line of the window glass having a heating couductor. CONSTITUTION:The antenna 21 for very high frequency stretches out in parallel with the heating conductor 12 from the start point 17, its tip is bent in a channel shape, also passes through the connection point 24 in parallel, and the tip forms an opening terminal. Also, the connection point 24 is connected to the connection point 26 on the heating conductor 12. And, the line connecting the start point 16 and the connection points 24, 26 is in parallel with the longitudinal center line of the flat glass 1, and also it is shifted from the center line. When such an antenna for very high frequency is installed, length of the antenna can be set to desired length irrespective of size of the window glass, and therefore, it is possible to increase the gain as to incoming radio waves from the front and the rear of a car, and elevate the nondirectional characteristic. |
