Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna system and network equipment. Background technique [0002] With the rapid development of mobile services, the demand for spectrum in cellular mobile communication systems has increased dramatically. However, the available spectrum resources of Sub6GHz low frequency are relatively scarce, and the evolution of the cellular mobile communication system to the millimeter wave (mmWave) frequency band has become an inevitable trend. [0003] The millimeter wave frequency band faces several outstanding problems: 1. How to solve the problem of high electromagnetic wave transmission loss, for example: the propagation loss of 60GHz in the air is about 22dB higher than that of 5GHz. The 60GHz wavelength is only 5 millimeters (mm), so there is basically no diffraction and diffraction in space transmission, the penetration loss is 30dB-40dB, and it is basically impo...

Problems solved by technology

[0003] The millimeter wave frequency band faces several outstanding problems: 1. How to solve the problem of high electromagnetic wave transmission loss, for example: the propagation loss of 60GHz in the air is about 22dB higher than that of 5GHz

The primary wall reflection loss is about 10dB, and the secondary wall reflection loss is about 16dB

2. Millimeter wave systems generally use narrow beam coverage, and the coverage of a single beam is limited. Therefore, it is necessary to provide coverage in multiple directions

However, for multi-directional coverage requirements, the industry mainly adopts simple phased array antennas and physical placement of multiple antennas. These technologies are difficult to implement and have low performance. For example, phased arrays are mainly single-beam, and multi-beam gain Such indicators are poor; physical placement / stacking of multi-beam antennas is bulky and difficult for engineering applications

Therefore, the existing multi-beam antenna technology is difficult to meet the simultaneous multi-beam and multi-user coverage requirements of future mobile communication and fixed access communication.
