      A dual-band dual-polarized magneto-electric dipole antenna for 5G micro base station

      • 摘要: 小型化是进行5G微基站天线设计的重要考虑因素,文中设计了一款适用于5G微基站的电磁偶极子天线. 天线由一对正交放置的单极化电磁偶极子、一对交叉放置的渐变式Γ形馈电线、一个圆形寄生贴片和一块正方形反射板组成,工作频段为2.50~3.62 GHz和4.8~5.0 GHz,能够覆盖工信部规定的5G的全部中频段. 在工作频带内,天线的输入回波损耗小于−10 dB;端口隔离度在低频段小于−25 dB,在高频段小于−42 dB;仿真平均增益在高、低频部分分别为5.57 dBi和9.84 dBi. 该天线能够实现双频段和双极化,可以作为小型化微基站天线设计的参考,同时为5G天线的商用化提供参考.

         

        Abstract: Miniaturization is an important consideration for the design of 5G micro base station antennas. A magneto-electric dipole antenna suitable for 5G micro base stations has been designed and analyzed. The antenna consists of a pair of orthogonally placed single-polarized electromagnetic dipole antennas, a pair of cross-graded Γ-shaped feeders, a circular parasitic patch and a square reflector. Its working frequency band is 2.50−3.62 GHz and 4.8−5.0 GHz, which can cover all the mid-band of 5G specified by the Ministry of Industry and Information Technology. In the working frequency band, the input return loss of the antenna is less than −10 dB; the port isolation is less than −25 dB in the low frequency band and less than −42 dB in the high frequency band; the simulated average gain is 5.57 dBi and 9.84 dBi in the high and low frequency parts, respectively. The antenna can achieve dual frequency bands and dual polarization, which can be used as a reference for miniaturized micro base station antenna design. The antenna provides a reference for the commercialization of 5G antenna.
