Vehicle surroundings monitoring device
First Claim
1. A vehicle surroundings monitoring device which monitors a peripheral area surrounding a vehicle, said device comprising:
- a transmitting antenna which is mounted in the interior of a door mirror of the vehicle, and which radiates transmitted waves through the surface of the door mirror; and
a receiving antenna that receives waves reflected from an object existing near the vehicle through the surface of the door mirror, wherein a frontward wave blocking structure which blocks unnecessary waves radiating toward the front of the vehicle is provided in a housing of the door mirror and at a supporting portion which supports the mirror surface of the door mirror and has the transmitting antenna and the receiving antenna built therein.

Abstract
In the vehicle surroundings monitoring device which monitors the surrounding of the vehicle, the device includes a transmitting antenna (2) mounted in the interior of the door mirror of the vehicle and radiates transmitted waves through the mirror surface of the door mirror; and a receiving antenna (3) that receives the reflected waves from an object existing near the vehicle through the mirror surface of the door mirror, a housing (12) of the door mirror and a support portion (15) that supports the surface of the door mirror (7) and has the transmitting antenna (2) and the receiving antenna (3) built therein are made of an electromagnetic shielding material. Instead, an electromagnetic shielding material is arranged on the inner surface of the housing and the inner surface of the door mirror support portion. Instead, an electric wave absorber is arranged on the inner surface of the housing and the inner surface of the door mirror support portion.
