Abstract

An antenna feeding network (2) for a multi radiator antenna (1) is provided. The antenna feeding network comprises at least one coaxial line (20a, 20b). Each coaxial line comprises a central inner conductor (14a, 14b) and an elongated outer conductor (15a, 15b) surrounding the central inner conductor, wherein at least one of the outer conductors of the coaxial lines is provided with an opening (40), wherein the antenna feeding network further comprises at least one nonconductive holding element (8) configured to be placed in the opening. The holding element is configured to hold at least one of the inner conductors in position. The invention further relates to a multi radiator antenna (1) comprising such an antenna feeding network (2), and to a method for providing an electrical connectionin such an antenna feeding network.

Description

technical field [0001] The invention relates to the field of antenna feed networks for multi-radiator antennas, said feed network comprising at least two coaxial cables. Background technique [0002] Multi-radiator antennas are often used, eg in cellular networks. Such multi-radiator antennas comprise several radiating antenna elements, for example in the form of dipole antennas, an antenna feed network and a conductive reflector for transmitting or receiving signals. The antenna feed network distributes signals from the shared coaxial connector to the radiators when the antenna transmits, and combines the signals from the radiators and feeds the signals to the coaxial connectors when receiving. exist figure 1 A possible implementation of such a feed network is shown in . [0003] In such a network, if the splitter / combiner consisted of only one junction between 3 different 50 ohm wires, then impedance matching would not be maintained and the impedance seen from each port...
