Problems solved by technology

On the other hand, due to engineering constraints such as appearance, wind resistance, load-bearing, and cost, the size of the antenna array cannot be too large, which contradicts the demand for a large number of antennas

Embodiment Construction

[0048] The following reference Figure 1-18 Embodiments of the present invention will be described.

[0049] figure 1 It is a structural diagram of an example of an antenna array according to an embodiment of the present invention. figure 2 It is a schematic diagram of an embodiment of the present invention.

[0050] MIMO performance is greatly affected by MIMO channel correlation. The stronger the MIMO channel correlation is, the worse the MIMO performance will be. Under the same wireless channel conditions, MIMO channel correlation is related to the phase difference of wireless signals between antennas. Generally speaking, the smaller the distance between adjacent antennas, the smaller the phase difference of the wireless signals between the antennas, and the stronger the correlation of the MIMO channel. In order to improve the MIMO performance per unit size of the antenna array, the embodiment of the present invention uses a radio frequency lens to increase the phase ...

Abstract

An antenna array and a wireless device using the antenna array are disclosed. The antenna array includes a first set of antennas and a first set of radio frequency lenses. Wherein, the first antenna set includes multiple antennas, and the first radio frequency lens set includes multiple radio frequency lenses. The plurality of antennas and the plurality of radio frequency lenses are regularly arranged. This rule enables the first set of radio frequency lenses to increase the phase difference of the wireless signal between the antennas.

Description

technical field [0001] The present application relates to the communication field, and in particular to an antenna array and a wireless device. Background technique [0002] Multiple-input and multiple-output (English: multiple-input and multiple-output, MIMO) uses antenna arrays to send and receive signals to improve wireless communication capacity. Widely used wireless transmission technology. For example, the 4th generation (English: 4th Generation, 4G) mobile communication system called Long-Term Evolution (English: Long-Term Evolution, LTE) and the new wireless (English: 5th Generation, 5G) mobile communication system of the fifth generation (English: English: New Radio, NR), and WLAN, both increase the system capacity by increasing the number of antennas. For example, the number of antennas can exceed 64 in LTE and NR, and can reach 16 in WLAN. According to the MIMO principle, the interval between adjacent antennas in the MIMO antenna array needs to be at least 0.5λ...
