摘　　要：本文提出一种新型的可共形于圆柱载体的阵列天线.采用共面波导（CPW）串联馈电的方法实现了较宽的工作带宽.在此基础上,研究了圆柱形载体对该共形阵列天线性能的影响.结果表明：没有载体时,共形阵列天线的-10dB带宽为2.1～3.45GHz（相对工作带宽48.6%）,最大增益为5.4dBi.加载相对介电常数介于1～8之间、厚度介于0～12mm之间的柱形圆管载体后,该共形阵列天线依然满足覆盖无线局域网（WLAN）2.4～2.48GHz的带宽要求,并且可以在-60℃～100℃的环境温度下工作,满足目前复杂的无线通信设备的使用需求.In this paper,a novel conformal antenna array for cylindrical structure is proposed.By employing the method of coplanar waveguide（CPW）series-fed,a wide bandwidth is realized.Then,based on that the effect of cylindrical carrier on the performance of the conformal antenna array is studied.The results show that the-10 dB bandwidth of the conformal antenna array without cylindrical carrier is from 2.1GHz to 3.45GHz（the relative bandwidth is 48.6 %）.The maximum gain reaches 5.4dBi.when the antenna array is conformal in cylindrical tube with different relative dieletric constant（εr=1～8）,different thickness（0～12 mm）,it can still meet the bandwidth demand of from 2.4 GHz to2.48 GHz wireless local area network（WLAN）.And the usage requirement of currently complex wireless communication equipment,also,it can work under the environment temperature from -60 ℃ to 100 ℃.
