摘要

超宽带微带天线对于电磁脉冲系统等需要较大带宽的调制技术的通信应用非常重要。超宽带天线阵列的共形版本没有像平面天线阵列那样进行研究。为此，本文提出了一种共形超宽带天线阵列。设计的单元天线带宽为5 ~ 40ghz，平均峰值增益为3.34 dBi。设计了平均增益为6.67 dBi、带宽为6.87 ~ 40 GHz的1×2阵列。设计了1×3天线阵列。采用模拟回波损耗与实测回波损耗相一致的方法制作了单格天线。本文提出了一种超宽带1X3共形微带天线阵列，其谐振范围为4.885-40 GHz，在7 GHz时峰值增益为13.54 dBi。天线阵列采用半径为150mm、长度为2100mm的圆柱结构，并进行了仿真参数分析。

Super wideband conformal antenna array on cylindrical surface

Super wideband microstrip antennae are important for communication applications which involves modulation techniques which require larger bandwidths, such as electromagnetic pulse systems. Conformal versions of super wideband antenna arrays are not explored as that of planar antenna arrays. Hence a conformal super wideband antenna array is proposed in this paper. The bandwidth and average peak gain of unit cell antenna designed are 5-40 GHz and 3.34 dBi. A 1×2 array is designed with average gain of 6.67 dBi and bandwidth 6.87-40 GHz. A 1×3 antenna array is designed. The unit cell antenna is fabricated with simulated return loss in agreement with measured return loss. This paper proposes a super-wideband 1X3 conformal microstrip antenna array which resonates from 4.885-40 GHz with peak gain of 13.54 dBi at 7 GHz. The proposed antenna array is conformed onto a cylindrical structure of radius 150 mm and length 2100 mm and parametric analysis is done by simulation.
