A group antenna has at least two transducers disposed offset from one another. A network is provided to supply the transducers. The network comprises coaxial cables running between a distributor and/or summation circuit and the access, connection, and/or supply points of the associated transducer. The network comprises at least two different types of coaxial cable characterized by different phase velocities.

Supply network for a group antenna

The invention relates to an improved method for operating a phase-controlled group antenna as well as an associated phase shifter assembly and a phase-controlled group antenna, characterized by, inter alia, the following features: the phase shifter assembly is designed such that at least one of the following two conditions is met: R: R&#x2267;n+k ud/or Ph: Ph&#x2267;n+k, where Ris the largest radius, and Ris the smallest radius of a conductor segment () relative to the phase shifter assembly (), where k is a value of 0.2 and particularly 0.25, 0.30, or preferably 0.40.

An improved GPS mast module is characterized by the following features: the GPS mast module may be connected in a HF main transmission line () between a base station (BS) and an antenna assembly (ANT), in particularly a mobile radio installation, and the satellite signals from an internal or connectable GPS antenna (GPS-ANT) can be supplied by a directional coupler () to the HF main path ().

A dual polarized antenna with at least one dual polarized radiator device comprises a reflector () and longitudinal or transverse webs () provided at least on its longitudinal side and/or on its transverse side. The improvement is distinguished by the following features: at least one longitudinal web () and/or at least two longitudinal webs () provided with respect to the radiator device (') located in between and/or at least one transverse web () and/or at least two transverse webs () provided with respect to the radiator device (&#x2032;) located in between are positionally changeable directly or at least indirectly by pivoting and/or bending and/or deforming and curving.

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.

Feed network, and/or antenna having at least one antenna element and a feed network

An antenna, in particular a mobile radio antenna, operates in at least two frequency bands. Two or more dipole antenna elements are provided and are arranged in front of a reflector, which transmit and receive in two different frequency bands. The distance between the antenna element structure, the antenna elements or the antenna element top of at least one dipole antenna element for the higher frequency band is at a distance from the reflector plane which corresponds to at least 75% and at most 150% of the distance between an antenna element structure. An antenna element or an antenna element top of at least one dipole antenna element for the lower frequency band and the reflector plane, and/or the distance between the antenna element structure, the antenna elements or the antenna element top of at least one dipole antenna element for the higher frequency band is at a distance from the reflector plane which is greater than 0.4&#x3bb; and is preferably less than 2&#x3bb; with respect to the mid-frequency of the antenna element for the higher frequency.
