摘要

To meet the performance requirements of dual-polarized antennas, this paper presents a miniaturized high-gain wideband dual-polarized dipole antenna. The proposed antenna consists of a pair of crossed dipoles and artificial magnetic conductor (AMC) reflectors that surround the sides of the dipoles. The introduction of side AMC reflectors enhances the gain characteristics of the antenna. To improve impedance matching, four semicircular slots are loaded between the radiating arms of the dipoles. The combination of these two innovative approaches enables the antenna to achieve high gain and broadband performance. To verify the effectiveness of the design approach, an antenna was manufactured and tested. Test results show that the impedance bandwidth of the designed antenna covers multiple wireless communication bands, with a bandwidth of 2.16 to 3.9 GHz (57.43%) and an isolation better than 30 dB. In the frequency range of 3.16 to 3.9 GHz, the antenna achieves a gain exceeding 9 dBi, reaching a peak gain of 10.5 dBi.
