Problems solved by technology

[0003] However, due to the increasing number of electronic devices integrated on the terminal equipment, the area available for antenna array layout on the terminal equipment is also becoming smaller and smaller; thus, the number of antennas included in the antenna array layout in this area The number of antennas included in some antenna arrays in the millimeter wave module circuit is less than the number of antennas in other antenna arrays
The gain of the antenna array is usually related to the number of antennas included in the antenna array. As the number of antennas decreases, the gain of the antenna array decreases; resulting in poor performance of the mmWave module circuit in the area covered by the antenna array

example 1

[0092] A first processing unit connected to all the first antennas 1110 in the first antenna array 1100 is any one of the two first processing units, that is to say, all the first antennas 1110 are connected to the second antenna 1210 Multiplexing the first processing unit.

[0093] In Example 1, when the number N of first antennas 1110 is greater than 2*M, the number of multiple first processing units is N; when the number N of first antennas 1110 is less than 2*M, the number of multiple first processing units The quantity is 2*M.

example 2

[0095] A first processing unit 1310 connected to one or more first antennas 1110 in the first antenna array 1100 is any one of the two first processing units 1310 connected to the second antenna 1210, that is to say, the first processing unit 1310 connected to the second antenna 1210 Some of the first antennas 1110 and the second antennas 1210 in the antenna array 1100 are multiplexed by the first processing unit 1310 .

[0096] In Example 2, when the number N of first antennas 1110 is greater than 2*M, the number of multiple first processing units is greater than N; when the number N of first antennas 1110 is less than 2*M, the number of multiple first processing units The number is greater than 2*M.

example 3

[0098] The second antenna 1210 is connected to two first processing units, and one first processing unit connected to all the first antennas 1110 in the first antenna array 1100 is one of the two first processing units connected to the second antenna 1210 Any one, that is to say, all the first antennas 1110 and the second antenna 1210 are multiplexed with the first processing unit.

[0099] In Example 3, when the number of first antennas 1110 is N=2*M, that is to say, the number of first antennas 1110 is twice the number of second antennas 1210, then the number of multiple first processing units is N or 2*M.

[0100] Exemplarily, if the number of first antennas 1110 is 4 and the number of second antennas 1210 is 2, then the number of first processing units in the processing module is 4.

[0101] In the embodiment of the present application, the number of the first antenna is twice the number of the second antenna, and the second antenna is connected to two first processing un...

Description

technical field [0001] The embodiments of the present application relate to the field of terminal technologies, and in particular to millimeter wave module circuits and terminal equipment. Background technique [0002] The millimeter wave antenna module, referred to as "millimeter wave module circuit", is a device that includes a millimeter wave radio frequency (Radio Frequency, RF) front end and an antenna array. Due to the high attenuation of millimeter waves during radiation, the coverage area of ​​millimeter wave radiation is usually small. In order to expand the coverage of millimeter wave radiation, multiple antenna arrays are usually set up in different directions on the terminal equipment, such as figure 1 As shown, the coverage of the millimeter wave radiation can be superimposed on each other in different directions to expand the coverage of the millimeter wave radiation. Usually, the number of antennas in the multiple antenna arrays is set to be the same accordi...
