A Miniaturized All-Metal Dual-Polarized Antenna Array with Heat Dissipation Enhancement

In this paper, a miniaturized all-metal dualpolarized antenna array with heat dissipation enhancement is proposed for base station application. The size of the antenna array is 3x3 with its vertical spacing 77 mm and horizontal spacing 53 mm. The radiator is bent vertically to realize the miniaturization of the antenna without sacrificing original electromagnetic performance. The antenna operates in the band of 2496 MHz to 2690 MHz with an electrical down-tilting of 6°±1°. Due to the advantage of the all-metal design of the antenna, it has stronger heat dissipation performance in the natural thermal simulation environment compared with the ordinary dipole antenna array printed on the dielectric plate.
