    摘要: A multi-beam antenna (200, 204) comprises at least one curved surface (202), at least one dielectric substrate (16), and a plurality of end-fire antenna feed elements (14, 14.1) on the dielectric substrate (16). The at least one curved surface may be either reflective (202), refractive or diffractive. Electromagnetic waves launched from the antenna feed elements (14, 14.1) are directed at the at least one curved surface (202), and are either reflected, refracted or diffracted thereby. In one embodiment, the substrate is located within a light assembly (206), e.g. a vehicle headlight (210), wherein at least one source of light (208) is operatively associated with the dielectric substrate (16), and the at least one curved surface (202) comprises the concave optical reflector (218) of the light assembly (210).

    摘要: A plurality of antenna elements (16, 16.1, 16.2, 16.3) on a dielectric substrate (12) are adapted to launch or receive electromagnetic waves (21) in or from a direction substantially away from either a convex (14) or concave (134) edge (142) of the dielectric substrate (12), wherein at least two of the antenna elements (16, 16.1, 16.2, 16.3) operate in different directions (58). Slotlines (26) of tapered-slot endfire antennas (16.1) in a first conductive layer (18.1) of a first side (20.1) of the dielectric substrate (12) are coupled to microstrip lines (34) of a second conductive layer (18.2) on the second side (20.2) of the dielectric substrate (12). A bi-conical reflector (64, 140), conformal cylindrical dielectric lens (66), or planar lens (68) improves the H-plane radiation pattern. Dipole (16.2) or Yagi-Uda (16.3) antenna elements on the conductive layer (18.1) of the dielectric substrate (12) can be used in cooperation with associated reflective elements (96, 98, 108), either alone or in combination with a corner-reflector (100) of conductive plates (102) attached to the conductive layers (18.1, 18.2) proximate to the endfire antenna elements (16, 16.2, 16.3).
