Patent ID: 7936306

Claim:
Multilayer antenna of a planar construction, comprising: a first patch antenna with a plurality of planes and/or layers which are arranged along an axial axis with or without a lateral offset from one another, comprising: a first electrically conductive ground plane, a first conductive radiation plane arranged so as to lie offset transverse to the first ground plane and extended parallel thereto, a first dielectric carrier arranged between the first ground plane and the first radiation plane at least for a partial height and/or a partial region, wherein the first radiation plane is electrically connected to an electrically conductive feeder, a first carrier provided directly or indirectly on the opposite side of the first radiation plane from the first ground plane, an electrically conductive parasitic patch arrangement, provided on the opposite side of the first carrier from the first radiation plane, wherein the first carrier has a thickness or height smaller than a thickness or height of the parasitic patch arrangement, wherein the parasitic patch arrangement is configured so as to be box-shaped or box-like and/or comprises, at least in regions, circumferential raised portions, rim portions, web portions or wall portions, which extend so as to proceed transversely from a base portion or central portion of the parasitic patch arrangement, specifically away from the first radiation plane, and a second patch antenna comprising a second dielectric carrier and a second radiation plane provided above the base portion or central portion of the parasitic patch arrangement, the second radiation plane being provided on the upper side, opposite the base portion or central portion of the second dielectric carrier, and the second patch antenna buried at least in part in the parasitic patch arrangement, is formed, completely or in part, as electrically conductive planes, which are provided on the second patch antenna at least in partial regions on the circumferential edge surface or outer surface thereof.
