中文摘要：

在现代通信中,为了实现在相同空间内装备更多的通信设备,需要让不同的通信设备共用同一天线,为了解决实际使用需求和耦合等干扰问题,设计了一款采用特殊的加载方法来实现低剖面宽频段的全向天线。对该天线的辐射原理、电磁特性及敏感参数等问题进行了讨论和仿真分析,并制作出了样机天线。对样机天线进行了实际测试,测试结果证实该天线具有低剖面、宽频带和全向辐射特性,与分析结果相一致,因此该天线能够解决在有限空间内装备更多的通信设备的实际使用需求。

英文摘要：

In modern communication,several communication devices need to share one antenna for integrating more communication devices in limited space.A low-profile wideband omnidirectional antenna is designed with special loading method for solving practical requirement and coupling disturbance.The radiation principle,EM characteristics,and sensitive parameters of this low-profile wideband omnidirectional antenna are simulated and analyzed.The antenna prototype is also manufactured.Practical test was processed on antenna prototype.And test result verified that the antenna has low-profile,wideband omnidirectional characteristics,which consists with analysis result.The antenna can meet the requirement that integrating more communication devices in limited space.
