摘　　要：研究了含平面等角螺旋天线阵列复合材料的微波吸收特性,并对天线阵列的吸波机理进行了初步的探讨。结果表明:含平面等角螺旋天线阵列复合材料的吸波性能与天线的起始半径、外半径和两臂间电阻阻值密切相关,经合理设计,吸波材料的有效带宽达6.64GHz,最大吸收峰值-19dB。Microwave absorbing properties of composites containing the planar equiangular spiral antenna array are investigated,and the absorbing mechanism of the planar equiangular spiral antenna array is briefly discussed.Results show that the absorbing performances of composites are affected greatly by the initial radius,the outer radius and the magnitude of resistance connecting two arms.If properly designed,the composite containing the antenna array can show a reflection loss blow-10dB in the frequency bandwidth 6.64GHz and the maximum absorption reaches-19dB.
