平２−１７２３０４号公報により提案されている。2. Description of the Related Art Conventionally, automobiles used in the UHF band
The structures of various antennas are being studied in the fields of aircraft telephones and satellite communications. In particular, a system is known in which the signals of GPS satellites are used to detect the position of an automobile. As an antenna used for this, a microstrip antenna (MS antenna) which is conventionally mounted on the exterior part of an automobile has been proposed by Japanese Patent Laid-Open No. 172304/1990.

補っていた。In this conventional example, it is indispensable to install an amplifier in the vicinity of the antenna in order to reliably receive a weak signal transmitted from a GPS satellite, and the normal direction of the antenna formed on a plane. Is required to be close to vertical. However, in the case of a glass antenna formed on the rear glass of an automobile, the normal direction of the rear glass is often installed near the horizontal due to the limitation of the automobile design and the field of view, and therefore the antenna stripe pattern was optimized. ..

い欠点を有している。As the miniaturization of antennas progresses, 1/2 to 1/4 of the carrier wave, especially in the UHF band.
When the size of the antenna is set to the wavelength, the high frequency energy received by the antenna is weak and it is difficult to transmit it to the receiver via the coaxial cable. Therefore, an amplifier is required in the vicinity of the antenna, but in the case of a planar antenna for automotive applications, the directivity depends on the directivity, and the amplifier is not always sufficient. In particular, the angle setting of the antenna formed on the rear glass surface of an automobile is limited by the design of the vehicle model, and the antenna surface has a drawback that it is difficult to receive because the normal direction is almost horizontal.
