The situation that shortest distance x1 is+0.2 or more and+0.8 or less is shown.On the other hand, when shortest distance x1 be 0 more than and less than+
It is more than necessarily to increase to the length of power supply 41 from the left frame side edge 71b, therefore from architrave in left frame edge 71b lateral edge when 0.2
The cost or weight of the power cable of 71a wiring increase.
Equally, the upper architrave 71a wiring of the right architrave 71c lateral edge window frame 71 from window frame 71 and with power supply 41 directly or
The power cable connected indirectly is capable of on the point of shortening, and shortest distance x1 is preferably -0.8 or more and -0.2 or less.It is another
Aspect is more than necessarily from the side right architrave 71c to the length of power supply 41 when shortest distance x1 is more than -0.2 and is 0 or less
Increase, therefore increases from the cost or weight of the power cable of architrave 71a wiring in right architrave 71c lateral edge.
It should be noted that the concrete example as the power cable directly or indirectly connecting with power supply 41, can enumerate
Coaxial cable or feed line etc..
In Fig. 1, on the point for the antenna gain that can be improved vertically polarized wave, along longitudinally extending for rear glass 100
The maximum length h10 of at least one stave is preferably 10mm or more and 45mm or less.Maximum length h10 is more preferably 12mm
Above and 40mm or less.When maximum length h10 is less than 10mm, it is difficult to ensure the antenna gain of vertically polarized wave.On the other hand,
When maximum length h10 is more than 45mm, it is difficult to ensure the configuring area of power supply 41.About this point, the configuration of antenna 10 is being hidden
