  • the 5G antenna includes at least three radiation units 10 which are disposed to be equally spaced apart from each other in a preset distance.
  • three radiation units 10 are utilized to constitute a subarray, and the spacing between two adjacent radiation units 10 is preferably 62.5 mm.
  • four subarrays can constitute a 5G antenna array, and the spacing between adjacent subarrays is preferably 52 mm. Therefore, the sizes of the radiation units 10 can be adjusted according to actual frequency requirements to meet the different operating frequency requirements, and the radiation units 10 are used in combination to meet 5G antenna requirements, so that as compared with other array antennas, the pattern of the 5G array antenna are improved significantly and have good standing waves, as shown in Fig. 6 ; the beam widths in the horizontal plane all reach 60° or more, as shown in Fig. 7 .
