Embodiment Construction

[0012] The invention is based on the knowledge that an existing antenna element 1 can be influenced by changing its environment, that is to say shape parameters such as fixation and area parameters, for example in combination with carrier 9, metallization 10 and dielectric 11 The patch antenna element, so that the antenna radiation characteristics can be adjusted over a wide range. This concept is schematically shown in FIG. 1 . The adjustment possibility is at least one shape parameter of the conductive surface 2 in combination with a shape parameter of the spacer 3 between the conductive surface 2 and the antenna element 1 . The spacing device 3 can be embodied in different shapes, which is shown in FIG. 1 in the shape of a cuboid with the opening 7 and the edge 8 belonging to the opening 7 and the support body 4 . The invention is based on the fact that the radiation properties of the antenna can be influenced not only by dimensioning the opening 7 , the support 4 and the ...

Abstract

The invention relates to an antenna arrangement comprising an antenna element (1) which is mounted in front of on a conductive surface (2). At least one form parameter of the spacer (3) between the antenna element (1) and the conductive surface (2) and at least one form parameter of the conductive surface (2) is taken into account for adjusting the antenna beam characteristics.

Description

Background technique [0001] Antennas that can be built in a simple and compact manner are especially advantageous for receiving satellite services such as SDARS or GPS. The radiation characteristics, that is to say the antenna pattern, must additionally be adjustable to the requirements of different services. Patch antennas are commonly used today which can be produced both compactly and cost-effectively and which can also provide the (left-handed / right-handed circular) polarization required for satellite services. However, the adjustability of the antenna pattern (gain as a function of elevation and azimuth) in these antennas is only limitedly possible. [0002] An antenna arrangement is known from WO 02 / 431183 A1 with a patch antenna element which is arranged at a distance in front of a conductive surface. There, measures are taken for the exact and reproducible fixing of the patch antenna element relative to the conductive surface. [0003] EP 0716470 B1 discloses a simi...
