Motor vehicle antenna for e.g. terrestial mobile radio, has discone/cone antenna with electrically conductive surface formed according to type of cone or triangle or trapezoid, where surface is aligned transverse to base/measuring surface

摘要

The antenna has a planar- inverted- F- antenna (PIFA) or linear-inverted-F-antenna (LIFA), where linear emitting devices of the antennae (PIFA, LIFA) and discone or cone antenna (5) are arranged in a distance to a base or mass surface (3) . The devices of the antennae (PIFA or LIFA) are connected with a base or mass surface by a short circuit.The discone or cone antenna has an electrically conductive surface (11), which is formed according to the type of a laminar cone or approximately according to the type of a triangle or a trapezoid. The surface is aligned transverse to the base/measuring surface.
