Abstract :
The ultra low profile inverted L antenna, whose horizontal element is bent as a meander line shape, is proposed and numerically analyzed for the reception antenna for the keyless entry system of automobiles at 315 MHz band. In the case of the conducting plane of 70 mm by 350 mm and the antenna height of 31.7 mm, the directivity of 2.48 dBi is obtained. In the numerical analysis, the electromagnetic simulator WIPL-D based on the Method of Moment is used.
