Integrated feeding network of 4G antenna

Abstract

The invention discloses an integrated feeding network of a 4G antenna. Through a reasonable arrangement and using the planarity design of a transmission line and a phase shifter assembly, a combiner network and a phase shifter network are combined into a whole. Therefore, complexity of a common network is effectively reduced, extra loss and production cost which are caused by an existing network connection mode are effectively reduced, assembly difficulty is greatly reduced, and the performance of the antenna is greatly improved. The integrated feeding network is compact in overall structure and has a qualitative leap in reliability and uniformity of volume production.

Description

technical field [0001] The invention relates to the field of mobile communications, in particular to an integrated feed network for 4G antennas. Background technique [0002] With the further increase of urban population density and business volume, and the popularization of 4G networks, the optimization of base station components has attracted more and more attention, especially in the field of electronically adjustable antennas. Problem: At present, the components of the electronically adjustable antenna on the market are set separately. When the number of oscillators of the electrically adjustable antenna reaches a certain number, the number of phase shifters and combiners will increase accordingly, and the number of oscillators, phase shifters, and phase shifters will increase accordingly. Both the coaxial cable and the combiner use coaxial cables for signal connection. Therefore, when an electronically adjustable antenna has many vibrators, its wiring network will becom...

[0002] With the further increase of urban population density and business volume, and the popularization of 4G networks, the optimization of base station components has attracted more and more attention, especially in the field of electronically adjustable antennas. Problem: At present, the components of the electronically adjustable antenna on the market are set separately. When the number of oscillators of the electrically adjustable antenna reaches a certain number, the number of phase shifters and combiners will increase accordingly, and the number of oscillators, phase shifters, and phase shifters will increase accordingly. Both the coaxial cable and the combiner use coaxial cables for signal connection. Therefore, when an electronically adjustable antenna has many vibrators, its wiring network will become very complicated and the assembly is extremely difficult. Therefore, the equipped electronically adjustable antenna is often It will make mistakes, which seriously affects the assembly quality, indirectly increases the production cost of the enterprise, and also buryes hidden dangers for the future assembly quality. Due to the difficulty of wiring and the complexity of the network, its volume will inevitably increase and its performance will be low; and currently due to The requirements of the 4G network for the frequency band often cannot solve the problem of integrating the two systems together, making it difficult to form an integrated feeding network, which in turn restricts the development of electronically adjustable antennas
