Abstract:
The present disclosure is related to an antenna system for a vehicle, such as a vehicle that has a non-metallic roof. The antenna system includes two metallic supports coupled to the roof. Additionally, the antenna system includes a first MIMO antenna pair. A first antenna of the first MIMO antenna pair is coupled to a first support of the two metallic supports, and a second antenna of the first MIMO antenna pair is coupled to a second support of the two metallic supports. The antenna system further includes a second MIMO antenna pair. A first antenna of the second MIMO antenna pair is coupled to the first support of the two metallic supports, and a second antenna of the second MIMO antenna pair is coupled to the second support of the two metallic supports. Yet further, the two metallic supports of the antenna system are physically separated from each other.
Abstract:
Systems and techniques are provided for a spiral light antenna. An antenna element may include a first curved element disposed orthogonally to a second curved element. The first curved element and the second curved element may be connected at a connection point at a center of the first curved element and a center of the second curved element. The antenna element may have rotational symmetry and origin symmetry though the connection point but not linear symmetry. The first curved element may be longer than the second curved element. A feed may be connected to the antenna element at the connection point perpendicular to the plane of the antenna element. The first curved element may be inductive, and the second curved element may be capacitive. The antenna element may be disposed at the front of a light bulb and the feed may extend towards the back of the light bulb.
