Abstract
A tripolar antenna is described having at least two electromagnetic signal transmitting/receiving elements arranged such that their axes of signal transmission/reception sensitivity are not parallel, wherein said elements are provided on or at least partially in a substrate of dielectric material so portions of said at least two elements are coplanar and dielectrically isolated from one another. In a preferred arrangement, two dipoles are provided on the substrate in perpendicular orientation and in the plane containing of the surface of said dielectric material. Most preferably a further third element is provided so as to render the antenna tripolar, said third element comprising a first circular disk element secured to an upper surface of the dielectric material, and a second slightly larger circular disk element, concentrically positioned on the corresponding opposite and lower surface of the dielectric.
