| 摘 要： | 机载的安装环境对机载设备的尺寸和重量提出了更高的要求。全向天线是近距离空间链路信号传输的有效技术手段,设计一种机载重量轻、小型化的全向天线具有非常重要的现实意义。区别于传统马刀天线,所设计的天线在尺寸、重量上得到了很大的缩减;为了满足共形要求,天线采用了微带形式,2 mm 的剖面能够根据载体的具体形式进行共形设计;采用双臂组合单极子形式进行阻抗加载,天线实现了超过50% 的驻波带宽(驻波小于2. 5)。通过测试,天线样机的实测性能与仿真结果吻合很好。

| Abstract: | The installation space and weight are taken as constraints of the airborne antenna. Omni-directional antenna is a useful method to transit the signals for short range communication, it is necessary to design an antenna with low weight and small size. Different with the knife-edge monopole antennas, this paper present an double arm microstrip monopole antenna. The antenna has a low profile of 2 mm, which can be used as conformal antennas. Besides this antenna provides a wide VSWR band over 50%. The measured results show the validity of the design based on simulation. |
