The return loss of unit approaches, the isolation highest with adjacent array element, then as therewith apart from increased array element, therebetween every
It is also gradually reduced from degree.
Figure 12 for unit 8 array antenna in 37GHz in XOZ planes along the scanning figure in Theta directions.By can in Figure 12
See and compared with antenna element, gain of the array antenna in +Z direction increases to 11.1dBi or so from 1.7dBi.In addition, from figure
In 5 it can also be seen that when the array antenna is scanned in 0 to 60 degree, secondary lobe will not increase it is too big, thus can and base
It stands and realizes point-to-point connection or communication.
Figure 13 for unit 8 array antenna in 38.6GHz in XOZ planes along the scanning figure in Theta directions, by Figure 13
As it can be seen that gain of this array antenna in +Z direction is 11.26dBi or so.Directional diagram secondary lobe in Figure 13 is relatively low, both less than
0dBi, main lobe can well scan in 0 to 60 degree.
Figure 14 for unit 8 array antenna in 40GHz in XOZ planes along the scanning figure in Theta directions, by can in Figure 14
See, gain of this array antenna in +Z direction is 11.37dBi or so.Main lobe in Figure 14 can be in 0 to 60 degree well
Scanning, secondary lobe are relatively low；But in 60 degree of main lobe, secondary lobe rises to more than 0dBi.
It can be seen that, as scan angle increases, secondary lobe also can be with rising from the scanning figure of Figure 12-14；With frequency
Increase, in the case of fixed cell spacing, the main lobe of antenna can narrow, and secondary lobe can rise.This is because frequency increases, wave
Length is reduced by, and corresponding wavelength multiples will increase under identical spacing, when scan angle is bigger, more it is possible that comprising bigger more
More secondary lobes.The antenna element and array antenna extend also to other 5G millimeter waves working frequency range.In addition, from Figure 12-
It can also be seen that this Antenna Design can ensure in the range of working frequency 37-40GHz in 60 degree of scan angles in 14 scanning figure
Inside work well.
