Abstract
Official abstract text for this publication.
The invention relates to an antenna device having a printed circuit board and at least one antenna radiator which is arranged on the printed circuit board and can be excited by the printed circuit board or a coupling window arranged thereupon, which radiator is designed in such a manner that it comprises at least two polarisations, which are preferably orthogonal to each other, and at least two resonance frequency ranges which are continuous or different to one another and at an interval from one another, wherein the antenna radiator comprises: at least one first dielectric body mounted on the printed circuit board and designed as a resonator, having a first relative permittivity, at least one second dielectric body designed as, having a second relative permittivity, wherein the first relative permittivity is greater than the second relative permittivity and wherein the second dielectric body is formed in such a manner that it is arranged over the at least one first dielectric body in such a manner that it bundles or scatters the electrical field in a plane orthogonal to the main beam direction at least in one of the resonance frequency ranges. The invention also relates to an antenna array.
First claim

The invention claimed is: 1. Antenna device, having a printed circuit board; and at least one antenna radiator arranged on the printed circuit board and excitable by the printed circuit board or by a coupling window arranged thereupon, which the radiator is designed in such a manner that the radiator comprises at least two polarizations, which are orthogonal to each other, and at least two resonance frequency ranges which are continuous or different to one another and at an interval from one another, where the antenna radiator comprises: at least one first dielectric body mounted on the printed circuit board and designed as a resonator, having a first relative permittivity (εr1); and at least one second dielectric body designed as an integrated lens or as a radiator with travelling waves and/or as a second dielectric body comprised as a dielectric rod radiator, having a second relative permittivity (εr2), wherein the first relative permittivity (εr1) is greater than the second relative permittivity and wherein the second dielectric body is formed in such a manner that it the second dielectric body is arranged over the at least one first dielectric body in such a manner that the second dielectric body bundles or scatters the electrical field in a plane orthogonal to the main beam direction in at least one of the resonance frequency ranges. 2. The antenna device according to claim 1 , wherein the following applies for the first relative permittivity (εr1) and for the second permittivity (εr2): |εr1−εr2|≥10 and wherein the following applies for the first relative permittivity (εr1):εr1≥12 and wherein the following applies for the second relative permittivity (εr2):2≤εr2≤5. 3. The antenna device according to claim 1 , wherein the maximum thickness (D) and height (H) of the second dielectric body are governed by the following relationship to the wave length (λ) of the center frequency of the lowest resonance frequency range of the antenna and the effective relative permittivity (εr2) of the second dielectric body ( 2 ): 0.5 * λ π ( ɛ r 2 - 1 ) ≤ H ≤ 2.5 * λ π ( ɛ r 2 - 1 ) and / or 0.5 * λ π ( ɛ r 2 - 1 ) ≤ D ≤ 2.5 * λ π ( ɛ r 2 - 1 ) . 4. The antenna device according to claim 1 , wherein the maximum thickness D and the height H of the second dielectric body are governed by the following advantageous relationship between the maximum thickness (D) and the height (H): D =(1.0±0.5)× H , if designed as a lens or radiator, or D =(0.5±0.25)× H , if designed as a radiator. 5. The antenna device according to claim 1 , wherein the excitation of the first dielectric body occurs symmetrically in relation
