Abstract

In this paper, the effect of raindrops on an on-glass antenna is evaluated to appropriately design a C-band automotive antenna. A three-layer composite glass is used for the automotive window glass panel. The electromagnetic field analysis of a dipole on-glass antenna placed in the center of a 300 mm × 300 mm flat composite glass was performed. As a result, it was found that raindrop situation had no significant effect on the reflection characteristics of the antenna. However, the reflection coefficient of the antenna worsens when the raindrops were connected to each other and streaked in a direction parallel to the antenna.
