Embodiment Construction

[0032] figure 1shows a schematic three-dimensional view of a first exemplary embodiment of an antenna arrangement, as is employed in particular for the frequency range above 2 GHz, for example for the so-called wireless WiMAX technology.

[0033] For this purpose, the antenna arrangement includes a housing 1 , which is sometimes also referred to below as a radome.

[0034] The housing has an upper side 1a ( figure 2 ), the upper side is generally designed to be at least slightly spherical or convex transversely to the longitudinal extension of the housing, ie at least slightly bulged outward. At the two upper and (pointing in the radiation direction) outer boundary edges 3, the upper side 1a of the housing / radome merges in an arc into the side wall part 1b, which is likewise designed as Slightly bulging outward.

[0035] Viewed from the end side, in the exemplary embodiment shown, the cross-sectional shape of the housing / radome is trapezoidal in such a way that the upper s...

Abstract

An improved antenna device is characterised by the following features: an external length compensation device (35) is provided, permitting a differing length expansion of the housing / radome (1) relative to at least one of the at least two external mounting devices (15) for fixing the antenna device, at least one of the two mounting devices (15, 15'') is provided with an external length compensation device (35), which covers at least one mounting device (15, 15'') and a guide device by means of which the housing / radome (1) may be adjusted relative to the mounting device (15, 15'') in one direction of the antenna housing / radome (1) at least for one path length and the external length compensation device (35) with the guide device is designed such that even with fastened screws (37) play (41) remains between a section of the housing / radome (1) and a section of the mounting device (15) in order to permit an unhindered compensation movement between the mounting device (15) and the housing / radome(1).

Description

technical field [0001] The invention relates to an antenna arrangement according to the preamble of claim 1, in particular to an antenna arrangement in the form of an antenna array with a plurality of radiation antennas arranged mutually offset at least in the mounting direction. device. Background technique [0002] Antenna arrangements, in particular for stationary mobile radio stations, have been known for a long time. [0003] The mobile radio station usually includes an antenna arrangement, which is generally designed in the form of an antenna array and for this purpose comprises a plurality of transmitters arranged offset from one another, for example in the vertical direction, which are arranged in front of a reflector surface. The entire reflector does not have to be arranged vertically, but can be oriented at a defined angle relative to the vertical. The entire construction is then placed in a housing called a radome (Random), which appears "transparent" or "quasi...
