摘要：
An ultra-wideband tightly coupled array antenna with low profile is proposed in this paper. The tightly coupled array utilize the mutual coupling between elements to expand the array bandwidth, solves the problem of coupling suppression, and achieves the bandwidth expansion. This paper uses dual-polarized dipole array to reduce the array size and increase the gain. At the same time, the resistance absorption layer (RFSS) is located between the antenna and the floor to change reflection of the floor, expand the bandwidth while greatly reducing the profile. The dualpolarized antenna bandwidth of the dipole array can achieve 2 similar to 9.53 GHz (VSWR<3), the bandwidth ratio is close to 5:1, and the profile is lower than lambda(max)/15.
