摘要:
针对当前移动通信系统广泛使用的多辐射单元集成天线存在的问题,本文设计并制作了一款双频带偶极子单体天线。设计中,利用天线臂赋形扩展了主谐振点处带宽、天线臂局部延展并折弯实现了双频点、电容加载实现了频点飘移,使该天线工作频段能够覆盖分时长期演进(Time division long term evolution,TD-LTE)通信技术的全部制式。在1.8~3.0 GHz频段内,天线的仿真和实测反射系数(S11)曲线吻合较好,对应TD-LTE制式所有业务频段的S11低于-10 dB; 两个谐振点处的仿真和实测方向图吻合,符合偶极子天线的辐射特性; 在工作频段内增益稳定。
Abstract:
To solve the problem of the multiple radiation element integration antennas which are widely used in the mobile communication system,a dual-band dipole antenna is designed and fabricated in this paper.Utilizing the method of shaped-arm,the main resonance bandwidth is broadened; utilizing extension and bending of the antenna arms,dual band is realized; utilizing capacitor loading technology,the shift of frequency is realized.The above design make the operating bands cover TD-LTE standard of domestic 4G mobile communications.Simulated and experimental results of the reflection coefficient(S11)of the antenna are in good agreement in 1.8 GHz~3.0 GHz.The frequency range with S11 of below -10 dB covers all the service bands of TD-LTE standard.Simulated and experimental results of radiation patterns at two resonance points are also in good agreement which accords with the radiation performance of dipole antennas.Besides,the antenna has a stable gain over its operating bands.
