Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of oscillators, and particularly relates to a distributed decoupling broadband oscillator. BACKGROUND

[0002] With the acceleration of global mobile communication network construction and the continuous upgrading of mobile communication systems, multi-band fusion, broadband, miniaturization, high quality and the like have become the main consideration factors of modern antenna design. With the large-scale construction of communication base stations, the base station antenna needs to be compatible with the requirements of multiple systems such as 2G, 3G, 4G and 5G, and the frequency is more and more, the mutual interference coupling is more and more serious, and the overall development trend of the antenna is miniaturization, light weight and distributed flexible arrangement.

[0003] Common methods to reduce the coupling between different antennas include:

[0004] (1) covering a frequency selective surface (FSS) layer above the antenna;

[0005] (2) adding a decoupling feed network between two antennas;

[0006] (3) using a defective ground structure (DGS) antenna reflection floor; and the like.

[0007] Method (1) improves the isolation between two antennas by covering a frequency selective surface, but this method will increase the antenna profile height, and the frequency selective surface layer will affect the original antenna radiation.

[0008] Method (2) needs to add a coupled feed network, which makes the antenna feed more complex and increases the cost of the system.

[0009] Method (3) will cause part of the energy to leak from the defective ground, which will increase the back lobe radiation energy of the antenna and may affect other networks at the back end.

[0010] Therefore, the above problems need to be further improved. SUMMARY

[0011] The main purpose of the present application is to provide a distributed decoupling broadband oscillator, which uses a network decoupling branch loading technology to reduce the coupling between different antennas. This technology will not affect the radiation performance of the existing antenna, and only reduces the energy feeding in the frequency band that needs to be filtered.

[0014] The radiation module comprises a first radiator and a second radiator, the first radiator is connected and matched with the first radiation connection point, the signal input by the first radiation connection point is fed into the first radiator and the electromagnetic wave generated by resonance is radiated, the second radiator is connected and matched with the second radiation connection point, the signal input by the second radiation connection point is fed into the second radiator and the electromagnetic wave generated by resonance is radiated, and the size and shape of the first radiator and the second radiator are replaced to match different electromagnetic wave frequencies;
