Abstract

The invention discloses a main line phase distribution type feed network, and the network comprises a main transmission line, a final-stage transmission line and N-1 power dividers. The power dividersare connected in sequence through the main transmission line. The power dividers comprise a main power divider and N-2 auxiliary power dividers. The input end of the main power divider is connected to the feed end, and the two output ends of the main power divider are connected with the input ends of the auxiliary power dividers at the lower level through main transmission lines respectively; theinput end of each auxiliary power divider is connected with an upper-stage power divider, and at least one output end of each auxiliary power divider is connected with one output port through a final-stage transmission line. The invention also discloses a phase adjustment method and a large-scale array antenna. By moving the position of the power divider, the output port of the feed network can be adjusted to reach the designed phase so as to meet the phase requirement of the corresponding radiation unit; the transmission loss can be reduced; therefore, the circuit is simpler, and the line loss is lower.

Description

technical field [0001] The invention relates to the technical field of mobile communication, and more specifically, relates to a main line phase matching feed network, a phase adjustment method, and a large-scale array antenna. Background technique [0002] Massive MIMO, a large-scale antenna array, is considered to be one of the core technologies of 5G. The antenna array usually consists of N radiating elements (N≥2) and a phase shifting power distribution network. [0003] The function of the phase-shifting power distribution network is to realize the required power and phase distribution for each radiating element. The commonly used technology is to design a one-stage or multi-stage power divider, adjust the length of the output branch line of the last stage power divider, and realize the phase adjustment of each antenna radiation unit, which is called a split-line phase matching feed network. technology. The split-line phase-matching feed network technology adjusts th...
