This paper presents the design of a dual-polarized aperture-coupled microstrip antenna array for Sub-6GHz 5G
communication systems. The antenna operates at 3.5 GHz and consists of 4×4 square patches. The proposed 4×4 array antenna
feds by aperture-coupled feed line provide broadband bandwidth to operate in the N78 sub-6GHz 5G frequency band. The dualpolarized is presented, which gives two communications channels.
