Abstract

The invention discloses a phase shifting feed network. The phase shifting feed network comprises a plurality of phase shifters, a plurality of power dividing units and a drive unit, wherein each phase shifter comprises a suspended strip-shaped line structure composed of a conductor shielding cover, a second medium board and a U-shaped coupling line thereon, a parallel coupling line and a first medium board with the same, and a metal ground in a successive stacking mode. The first medium boards of the phase shifters are connected to form a connected medium board; the connected medium board is provided with the power dividing units; the phase shifters are symmetrically arrayed in two rows, and the parallel coupling lines of the adjacent phase shifters in the same row are connected through the power dividing units; the drive unit is connected with the second medium board of each phase shifter to synchronously drive several medium boards to move so as to enable the U-shaped coupling lines to move relative to the parallel coupling lines to realize the signal phase shifting. The phase shifting feed network is a hybrid phase shifting feed network which comprises the suspended strip-shaped line and a micro-strip line, and the hybrid phase shifting feed network is capable of realizing the phase shifting of a tunable antenna in higher integration level, better expansibility and more excellent performance.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a phase shifter, a phase shifting component including the phase shifter, and a phase shifting feed network. Background technique [0002] With the development of mobile communications, due to the complex and changeable network environment and the shortage of site selection resources, the requirements for base station antennas are usually higher. At present, the electric adjustable antenna is widely used, because the electric adjustable antenna can realize the continuous adjustment of the vertical pattern, and the network coverage is more flexible. [0003] The principle of the electrically adjustable antenna is to change the phase of the signal flowing through the phase shifter and fed to the antenna radiation unit through the relative movement of the conductor in the phase shifter, thereby changing the coverage orientation of the signal beam formed by the antenna. [0004] As the core c...
