Embodiment Construction

[0053] exist figure 1 shows a schematic front view of a multi-element antenna with a plurality of radiators 1 in front of a reflector 3 . In the exemplary embodiment shown, the multi-element antenna comprises six dual-polarized radiators or radiator arrangements 1a-1f.

[0054] Here, the radiator can consist of different radiators or radiator forms, including dipole radiators, crossed dipoles, so-called vector dipoles (known for example from WO00 / 39894A1), patch radiators, etc. Wait. This can be a single-band antenna, a dual-band antenna or a multi-band antenna which transmits and / or receives in three or more frequency bands. Likewise, single-polarized or dual-polarized antennas are possible. In this regard, reference is made to known solutions.

[0055] according to figure 1 The schematically shown antenna can be used, for example, in a base station of a wireless communication device.

[0056] In order to be able to adjust the deflection angle differently relative to th...

Abstract

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: RN : R1 = n + k ud / or PhN : Ph1 = n + k, where RN is the largest radius, and R1 is the smallest radius of a conductor segment (11) relative to the phase shifter assembly (7), where k is a value of 0.2 and particularly 0.25, 0.30, or preferably 0.40.

Description

technical field [0001] The invention relates to a method for operating a phase-controlled multi-element antenna according to the preamble of claim 1 and a phase shifter arrangement according to the preamble of claim 10 and to a phase shifter arrangement according to the preamble of claim 17 The corresponding phase-controlled multi-element antenna described above. Background technique [0002] Phase-controlled multi-element antennas are known, for example, from mobile communication technology. [0003] Mobile telephone antennas are usually used for base stations, and the mobile communication antenna consists of one or more columns arranged next to each other, in which a plurality of radiators or radiator groups arranged one above the other are arranged in each case. In this case, the radiator can be a single-polarized or dual-polarized radiator. The antennas can be designed as single-band antennas, dual-band antennas or also as multi-band antennas with radiators which can t...
