摘要
针对空间天线在移动通信中的应用,设计了一款适用于空间应用的高温超导超增益天线。采用开口谐振环结构,通过类似于八木天线的方式排列以实现天线的高增益,使用超导材料代替传统金属材料降低天线的损耗。仿真结果表明该天线工作在2.45 GHz,增益为7.29 dBi,实验测得天线增益为7 dBi,比哈林顿定义的相同尺寸的天线增益高2.01 dB。该天线具有小型化和高增益的特点,天线尺寸为22 mm×34 mm×0.5 mm。
For the application of space antenna in mobile communication,a high-temperature superconducting supergain antenna for space applications is designed.Split ring resonators are used and arranged in a manner similar to the Yagi antenna to achieve high gain,and superconducting materials instead of traditional metals are used to reduce the loss of the antenna.The simulation results show that the antenna works at 2.45 GHz and the gain is 7.29 dBi.The measured gain is 7 dBi,which is 2.01 dB higher than that of the same size antenna defined by Harrington.The antenna features miniaturization and high gain,with an antenna size of 22 mm×34 mm×0.5 mm.
