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 S11<-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%).
