Abstract

This research presents the design of time-modulated antenna arrays with UWB performance. The antenna arrays consider a linear topology with eight UWB disk-notch patch antennas. The technological problem is to find out the optimum antenna positions and/or time sequences to reduce the side lobes and the sidebands in all of the UWB frequency ranges. The design process is formulated as a bacterial foraging optimization. The results show that the uniform array generates a better SLL performance whereas the non-uniform array obtains a wider bandwidth. The uniform array obtains an SLL < −20 dB from 3.37 GHz to 4.8 GHz and the non-uniform array generates an SLL < −7 dB from 2.97 GHz to 5.26 GHz. The sideband levels are very similar for both cases with a value of around −17 dB.

摘要

本研究提出了具有超宽带性能的时间调制天线阵列的设计。该天线阵列采用具有八个超宽带圆盘槽口贴片天线的线性拓扑结构。技术问题在于找出最佳天线位置和/或时间序列，以降低所有超宽带频率范围内的旁瓣和边带。设计过程被表述为一种细菌觅食优化方法。结果表明，均匀阵列产生更好的旁瓣电平性能，而非均匀阵列获得更宽的带宽。均匀阵列在3.37吉赫兹至4.8吉赫兹范围内获得旁瓣电平＜-20分贝，非均匀阵列在2.97吉赫兹至5.26吉赫兹范围内产生旁瓣电平＜-7分贝。两种情况下的边带电平非常相似，值约为-17分贝。
