Feeding network, antenna and mobile communication base station

Abstract

A feeding network (20) for an antenna (14) has at least one lower level node (22), a plurality of upper level nodes (24), and a plurality of loads (26). The at least one lower level node (22) is electrically connected in parallel to a plurality of the upper level nodes (24) by lower level signal lines (28). The upper level nodes (24) are electrically connected in parallel to a plurality of the loads (26) by upper level signal lines (30). The upper level nodes (24), the respective connected loads (26) and the corresponding upper level signal lines (30) form subnetworks (32). The lengths of the upper level signal lines (30) of one of the subnetworks (32) differ from the lengths of the upper level signal lines (30) of at least one other of the subnetworks (32). Further, an antenna (14) and a mobile communication base station (10) are shown.
