摘要
采用耦合馈电、镜像技术、双枝节辐射以及曲流、多分枝扩展带宽等技术,设计频点为800MHz和2.5GHz的双频小天线。通过开槽来改变天线模式的分布从而实现多频工作,使用耦合馈电和多个谐振单元展宽频带的方法实现带宽展宽。由结果可知天线覆盖了多个通信频段。
The dual-frequency small antenna with 800 MHz and 2.5GHz frequency points was designed by using coupled feed, mirror technology, dual-branch node radiation and meandering, multi-branch extended bandwidth. By slotting to change the distribution of the antenna modes to achieve multi-frequency operation, bandwidth widening is achieved by using coupled feed and multiple resonant units to broaden the frequency band. The simulation results show that the antenna covers multiple communication bands.
