摘　　要：提出了一种基于碳-碳复合材料的耐高温小型天线,利用“外星人”辐射贴片和DGS结构,实现超宽带性能。此外,设计中还利用碳-碳复合材料作为导电材质,其良好的导电性以及优秀的耐热性,使整体天线能够长期在高温下正常工作,实现耐高温性能。仿真结果表明,该天线的S_(11)<-10 dB的阻抗带宽为4.45~16.53 GHz(相对带宽为115.16%),放入金属弹壳内的阻抗带宽为1~12 GHz(相对带宽为169.23%)。A high-temperature resistant small antenna based on carbon-carbon composite materials is pro⁃posed,which utilizes“alien”radiation patches and DGS structures to achieve ultra wideband performance.In ad⁃dition,carbon-carbon composite materials are used as conductive materials in the design,which have good con⁃ductivity and excellent heat resistance,enabling the overall antenna to work normally at high temperatures of 500℃and achieve high temperature resistance.The simulation results show that the impedance bandwidth of the antenna with S_(11)<-10 dB is 4.45~16.53 GHz(relative bandwidth is 115.16%),and the impedance bandwidth inside the metal shell is 1~12 GHz(relative bandwidth is 169.23%).
