In this paper; a wideband; dual-polarized antenna with extremely low profile is developed for base station application. The antenna evolved from two fan-shaped dipoles that crossed each other. By adding annular branches and met-allized through holes at the end of the dipole; its port input impedance increases when the antenna occupies a lower height. Besides; the flare angle of the fan-shaped arm is increased so that a second resonant point can be generated to achieve the purpose of expanding the bandwidth. The dual-polarized antenna can provide a bandwidth of 22% in the 2.17~2.7 GHz band. Because the two dipoles is highly symmetrical about the geometric center; the isolation degree and cross polarization discrimination are high in the working frequency band; among which the simulation value of the isolation degree can reach 51 dB; and the simulation value of the cross polarization discrimination in the 0° can reach 48 dB. In addition; the simulated peak gain of the antenna is as high as 9.6 dBi. The antenna has the advantages of high isolation; high cross-polarization discrimination and high gain; and has a good application prospect in the base station system. © 2024 Chinese Institute of Electronics.
