Embodiment Construction
[0041] exist figure 1 An exemplary embodiment of an antenna or mobile radio antenna, such as an antenna or mobile radio antenna that can be fixed, for example, on an antenna mast 3 or another suitable location is shown schematically in FIG.
[0042] Such antennas or mobile radio antennas generally comprise a housing or cover 5 with a radome 105 and an upper and a lower cover 5a. In particular, the connections provided for antenna operation, including coaxial connections and control connections, can be formed in the lower cover plate 5 a without restriction in this regard.
[0043] Such antennas or mobile radio antennas 1 usually stand assembled in a vertical direction or primarily in a vertical direction.
[0044] Such mobile radio antennas can also be designed as so-called active mobile radio antennas. In this case, the active mobile radio antenna has active high-frequency electronics, which are preferably integrated on the rear side into the antenna housing or mounted rear...

The invention relates to an improved capacitively shielded housing, in particular a capacitively shielded component housing for a mobile radio antenna, which is characterized, inter alia, by the following features: comprising an electrically conductive component and / or reflector housing (16), the component and / or reflector housing (16) has an opening region (30), which is shielded with respect to HF radiation by a shielding cover or a shielding plate (31), the contact or anchoring cover segments (45) of the shielding cover or of the shielding plate (31) are arranged against the component and / or reflector housing (16) immediately adjacent to and in parallel with the contact or anchoring housing segments (122), an insulating layer (47) being interposed, and the planar contact or anchoring housing segments (122) and the planar contact or anchoring cover segments (45) are oriented parallel to or at angle to an insertion or mounting direction (E) and / or a central axis (Z) extending through the component and / or reflector housing (16), namely at an angle alpha according to the following condition: 0 degrees < alpha < 90 degrees.
Description
technical field [0001] The invention relates to a capacitively shielded housing, in particular a capacitively shielded component housing for an antenna arrangement, such as a mobile radio antenna, for example, according to the preamble of claim 1 . Background technique [0002] According to current standards, for example in mobile radio technology, reflectors are used for radio base station antennas, said reflectors being designed like housings on their rear side opposite the radiator side. For example, wiring, phase shifters, adjustment devices for the phase shifters, filter components, etc. can be accommodated in such spaces. Here, the reflector can be provided with side wall webs which transition into a fastening flange terminating parallel to the reflector plane, onto which the reflector cover can be screwed, for example. [0003] Furthermore, in mobile radio antennas in accordance with today's packing densities, active components such as radios or also remote radio hea...
