Multilayer antenna arrangement

Multilayer antenna of a planar construction, comprising a patch antenna (A), preferably to the exclusion of an inverted F-antenna, with a plurality of planes and/or layers which are arranged along an axial axis (Z) with or without a lateral offset from one another, having the following features:

• an electrically conductive ground plane is provided
• a conductive radiation plane is provided, which is arranged so as to lie offset transverse to the ground plane and which preferably extends parallel thereto,
• a dielectric carrier is provided, which is arranged between the ground plane and the radiation plane at least for a partial height and/or a partial region, optionally in addition to air,
• the radiation plane is electrically connected to an electrically conductive feeder,
• it comprises carrier means, which is provided directly or indirectly on the opposite side of the radiation plane from the ground plane,
• it comprises an electrically conductive parasitic patch arrangement, which is provided on the opposite side of the carrier means from the radiation plane,
• the carrier means has a thickness or height which is smaller than the thickness or height of the parasitic patch arrangement,
• 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 radiation plane,
• characterized by the following further features:
• a further patch antenna (B) comprises a dielectric carrier and a radiation plane is provided above the base portion or central portion of the patch arrangement, the radiation plane being provided on the upper side, opposite the base portion or central portion of the dielectric carrier, and
• the further patch antenna (B) is buried at least in part in the parasitic patch arrangement, which is configured so as to be box-shaped or box-like, and/or the patch arrangement which is configured so as to be box-shaped or box-like is formed, completely or in part, as electrically conductive planes, which are provided on the further patch antenna (B) at least in partial regions on the circumferential edge surface or outer surface thereof.
