る。Reference numeral 1 is a quarter glass of an automobile, and reference numeral 2 is a conductor portion embedded in the surface of this glass l, which becomes a glass antenna. This conductor part 2 is parallel to the left and right sides of the glass 1, and includes first and second conductor parts 2a and 2b whose upper ends are provided at an intermediate height of the glass 1, and both conductor parts 2a and 2b. It consists of a third conductor part 3C connecting the upper end part. 3 is the conductor part 2a, 2b
A slit 4 between the vehicle body 5 and the vehicle body 5 is connected to the third conductor portion 2c and serves as a feeder line for extracting the received signal.

スリット3の両側に生じる電位差として電波を受信し、

波はボデー5による影響を受けることなく受信できる。The window glass antenna configured as described above receives radio waves as a potential difference generated on both sides of the slit 3 between the conductor 2 embedded in the quarter glass 1 and the car body 5,
The received signal is guided to the receiver by the power supply line 4, and the radio waves can be received without being affected by the body 5.

。Furthermore, since the conductor 2 is approximately U-shaped, it does not obstruct the outside scenery. Furthermore, the above-mentioned glass antenna can be considered as a type of loop-shaped slit in which the width of the slit changes. By widening the slit width above the feed point, the area above the feed line 4 is left open. This reduces the total length of the antenna by half (creates an image).
This allows for efficient use of small spaces. Furthermore, since the input impedance seen above and the impedance seen below the feeder line 4 are different, matching with the feeder line 4 is easy to achieve.
また、給電線4より下部のスリットにおいてはコ字形の
ように切込むことでスリットの途中でスリット幅を変え
る。これによって、スリットの全長が長くなり、共振周
波数を下げることができる。Further, the slit below the power supply line 4 is cut in a U-shape to change the slit width in the middle of the slit. This increases the total length of the slit and lowers the resonant frequency.
さらに、スリット幅が太くなることで広帯域となりかつ
、スリット幅を変えることで整合を取ることができる。Furthermore, by increasing the slit width, a wide band can be obtained, and by changing the slit width, matching can be achieved.

信号の受信を良好に行なうことができる。As explained above, according to this invention, radio waves are received by the slit between the conductor provided on the quarter glass surface and the body of the automobile, so that the radio waves are not affected by the body. Even if the glass is small, signal reception can be performed well.
