Abstract: An improved antenna arrangement includes a reflector arrangement comprising a printed circuit board with an electrically conductive ground plane. The reflector arrangement also has a reflector frame with a coupling surface. The coupling surface is capacitively coupled to the ground plane. The coupling surface has a recess via which the ground plane, which is located underneath it, and/or the printed circuit board or an isolating intermediate layer which is provided above the ground plane or an isolating intermediate layer which is provided above the printed circuit board is exposed. The at least one antenna element arrangement is positioned and/or held on the printed circuit board in the area of the recess.

Abstract: An improved antenna device has an internal length compensation device, permitting a varying length expansion of the housing/radome in relation to the antenna support or reflector device located within the housing/radome. At least one of at least two internal fixing devices is provided with the internal length compensation device. The internal length compensation device is in at least two parts or has two limbs, wherein one part is fixed to the antenna support and/or reflector device and the other part is at least indirectly fixed to the housing/radome and/or supported thereby. The at least two parts can be moved relative to each other, be moved in position or deformed. In particular with relation to the support points of both parts, the position may be changed with common deformation.

Abstract: An improved antenna device is has an external length compensation device, permitting a differing length expansion of the housing/radome relative to at least one of the at least two external mounting devices for fixing the antenna device. At least one of the two mounting devices has an external length compensation device, which covers at least one mounting device and a guide device by means of which the housing/radome may be adjusted relative to the mounting device in one direction of the antenna housing/radome. At least for one path length and the external length compensation device with the guide device is designed such that even with fastened screws, play remains between a section of the housing/radome and a section of the mounting device in order to permit an unhindered compensation movement between the mounting device and the housing/radome.

Abstract: An improved dual polarized radiator is distinguished, inter alia, by the following features: the dual polarized dipole radiator is made from a strip and/or board material, in particular a metal sheet, the dual polarized dipole radiator is constructed in one piece, and the individual portions of the dual polarized dipole radiator, including the dipole components, the feed arms, the support portions forming the balun and an associated base connecting the support portions, are connected to one another by bending and/or tilting and/or folding lines formed in the sheet-like basic material.

Abstract: An antenna feed network is provided with a capacitive coupling device via which a capacitive connection exists to a coupled line. The coupled line section is firmly connected to the downstream appliance or antenna element, or is part of the appliance or antenna element, in the region of the capacitive coupling device. The feed network has a first coupling section and the coupled line has a second coupling section. The two coupling sections are fixed with respect to one another by means of a bracket and/or holding device in a relative position such that relative movement between the two coupling surfaces can take place parallel to the coupling surface.

Abstract: An improved radome comprises at least one conductive flat structure integrally incorporated in the material of the radome, which acts as a reflector for a mobile radio antenna at least partially enclosed within the radome.
