Abstract
PURPOSE:To obtain omnidirectivity by arranging plural antennas constituted of a coil wound to a magnetic rod and a capacity on the flat roof of an automobile so that 0 deg. or 90 deg. cannot be mutually obtained, and feeding any one antenna among them. CONSTITUTION:On the flat roof of an automobile, plural antenna elements are arranged so that they cannot mutually become 0 deg. or 90 deg.. For example, antenna elements 1A-1C are arranged in a triangle way. For respective antenna elements 1A-1C, coils 3A,3A'-3C,3C' are wound to magnetic rods 2A-2C, capacity elements 4A,4A'-4C,4C' are provided in parallel and a parallel circuit is formed. Feeding is executed to 1A which is one of antenna elements. Thus, the antenna equipment with omnidirectivity can be formed.
