Problems solved by technology

In the case of a hood-shaped roof, however, this would necessarily lead to a considerable increase of the overall housing, because due to the defined curved outer contour of the housing, a slight increase in the minimum height already leads to an overall unsatisfactory size of the housing body. widen and lengthen

Embodiment Construction

[0056] First refer to the following Figures 1 to 4 In the embodiment shown therein is shown a patch antenna having a plurality of planes and layers superimposed along an axial axis Z. Such a patch element is known in principle from DE 10 2006 027 694 B3, the disclosure content of which is hereby incorporated in its entirety. However, the patch element known from DE 10 2006 029 694 B3 does not have a two-part parasitic patch arrangement comprising an additional patch element according to the invention.

[0057] by pressing figure 1 It can be seen from the schematic cross-sectional view that the patch antenna A has an electrically conductive ground plane 3 on its so-called bottom or mounting plane 1 . Arranged on the ground plane 3 or laterally offset therefrom is a dielectric carrier 5 , which generally has an outer contour 5 ′ in plan view, which corresponds to the outer contour 3 ′ of the ground plane 3 , although the dimensions of the dielectric carrier 5 are also The o...

Abstract

An improved multi-layer antenna is distinguished by the following features: the patch arrangement (13) is at least divided into two and comprises, in addition to the primary patch element (53), a secondary additional patch element (55), the patch element (53) and the additional patch element (55) can be positioned such that they can be moved towards one another and at least partially one in the other in order to change their overall height (114), and the additional patch element (55) is held by a separate holding and supporting device, preferably by a hood (61) which covers the entire antenna arrangement.

Description

technical field [0001] The invention relates to a multilayer antenna in the form of a planar structure. Background technique [0002] A multilayer antenna of the same type is known from DE 10 2006 027 694 B3. [0003] The multi-layer antenna in the form of a planar structure includes a dielectric ground plane, a conductive radiation plane (which is connected to the ground plane ( ) are arranged at parallel intervals) and a dielectric carrier, which is sandwiched between the ground plane and the radiation plane. A supporting device is arranged above the radiating surface, on which a conductive patch element is positioned. The support means of the patch element has a thickness or a height which is smaller than the thickness or height of the patch element. [0004] The patch element itself can be designed as a volume, that is to say as a solid body. It is also possible for the patch element to be formed from a metal plate or a metal sheet, which is provided, for example by...
