Omnidirectional flat antenna and method of production
First Claim
1. A flat antenna comprising:
- a flat substrate,a first flat coil formed on a surface of the flat substrate, the first coil having an axis perpendicular to the plane of the substrate,a first magnetic thin layer arranged on said surface of the substrate,a second coil having an axis parallel to the plane of the substrate and wound around the first magnetic thin layer,an electrically insulating layer arranged on the second coil and the first magnetic thin layer,a second magnetic thin layer arranged on the electrically insulating layer, anda third coil having an axis perpendicular to the axes of the first and second coils and wound around the second magnetic thin layer.

Abstract
The inventive antenna comprises a planar substrate carrying as first winding whose axis is arranged in a parallel position to the plane of the substrate. Said antenna also comprises at least one second winding, whose axis is arranged in a parallel position to the plane of the substrate and which is wound-up about a thin layer made of high magnetically permeable material and arranged in a parallel position with respect to the plane of the substrate. A third winding, whose axis is perpendicular to the first and second windings and which is wound-up about an additional thin layer can be provided. Said additional thin layer is arranged in a parallel position to the plane of the substrate and is made of high magnetically permeable material.
