Abstract

A roof module includes an antenna that is provided in a planar shape along a roof panel on a cabin inner side of the roof panel and transmits and receives electromagnetic waves. The roof panel is formed of a resin material in a planer shape and defines an exterior of a vehicle. The roof module also includes a metal panel that is formed of a metal material in a planar shape and provided along the antenna on the cabin inner side of the antenna. In this manner, the roof module can stabilize electromagnetic environments by the metal panel intentionally provided on the cabin inner side of the antenna in the vehicle the roof panel of which is formed of a non-metal material but a resin material.

Claims

1. A roof module comprising:
