摘要：

A broadband dual-polarized antenna for base station applications is presented. The dual-polarized antenna is composed of two perpendicularly crossed dipoles. Compared to a traditional dipole antenna, the presented antenna has a smaller size of 0.27x0.27x0.36 lambda(3). Miniaturization of the antenna is realized by bending the radiating arms of the antenna. The simulation impedance bandwidth of the antenna achieves 26% (3.02-3.96 GHz). Meanwhile, the port isolation is higher than 32 dB over the entire operational band. Furthermore, a two-element MIMO antenna is realized with a center-to-center spacing of 0.45 lambda, achieving a high isolation level between adjacent elements over the entire bandwidth through the decoupling structures designed in this paper. The proposed antenna's potential as an excellent unit cell of the base station antennas is verified by simulation.
