Problems solved by technology

[0004] When the number of antennas increases by adopting the existing scheme, the consumables, volume, weight and cost of the antenna unit 101 will be greatly increased, and the yield rate will be reduced.
At the same time, the isolation between the receiver 103 and the transmitter 104 is not enough, resulting in intermodulation problems, resulting in a decline in radio frequency indicators, or even completely unusable

Embodiment Construction

[0077] The invention provides an antenna system capable of effectively improving the isolation between a receiver and a transmitter. The structure of the antenna system provided by this embodiment will be described in detail first from the perspective of physical equipment:

[0078] The antenna system shown in this embodiment can have two structures:

[0079] a kind of like figure 2 as shown, figure 2 It is a schematic structural diagram of an embodiment of the antenna system provided by the present invention.

[0080] figure 2 The antenna system shown is a passive antenna architecture, and the antenna system includes an RRU (English full name: Radio Remote Unit, Chinese full name: Radio Remote Unit) 200, and the RRU 200 is provided with a transmitter and a receiver. The RRU 200 is connected to the antenna array 201 through a cable 202 .

[0081] The antenna array 201 shown in this embodiment includes multiple antenna units.

[0082] Specifically, in the application ...

Abstract

The embodiment of the present invention discloses an antenna system, including: a receiver set, a transmitter set, and an antenna array, the receiver set includes multiple receivers, and the transmitter set includes multiple transmitters; The antenna array includes a first antenna unit set and a second antenna unit set, the first antenna unit set includes at least one first target antenna unit, and the second antenna unit set includes at least one second target antenna unit, so Any first target antenna unit in the at least one first target antenna unit is connected to any receiver in the receiver set, and any second target antenna unit in the at least one second target antenna unit is connected to the Any transmitter connection in the transmitter set. Therefore, the receiver is completely isolated from the transmitter, thereby improving the isolation between the receiver and the transmitter, and effectively improving the intermodulation index of the antenna system.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an antenna system. Background technique [0002] With the development of wireless communication technology, in order to increase the system capacity, a multiple input multiple output (Multiple Input Multiple Output, MIMO) technology is proposed, which creates a demand for multiple antennas. MIMO can realize spatial multi-stream transmission through space division multiplexing and improve the capacity of the communication system; MIMO can improve the reliability of the communication system through diversity. MIMO technology achieves a substantial increase in capacity by increasing the number of antennas, but it also brings great challenges to the performance index PIM, consumables, volume, weight, cost, and yield of antenna design. [0003] In existing schemes, such as figure 1 The antenna array 100 includes a plurality of antenna units 101 in order to meet the re...
