摘要
为克服微带天线增益较低的限制并提高天线的整体性能,基于聚酰亚胺材料和十字形单元,提出并设计了一种超薄柔性可穿戴的高增益天线阵列.该天线阵列由16个十字形天线单元均匀分布在4×4的拓扑结构中组成,体积为72 mm × 72 mm × 0.4 mm,最大增益可达9.7 dBi,天线单元工作频段为5.75～5.83 GHz,中心频率为5.8 GHz,相比于现有文献的微带天线平均增益提升了3.87 dB.对天线阵列进行了实物制作及测试,测试结果与仿真结果吻合较好,证明了该设计方案的可行性和实用性.
Abstract
To overcome the limitation of low gain in microstrip antennas and to improve overall an-tenna performance,an ultra-thin flexible wearable antenna array with high gain is proposed and designed based on polyimide material and cross-shaped elements.This antenna array consists of 16 cross-shaped antenna elements uniformly distributed in a 4×4 topology,with dimensions of 72 mm×72 mm×0.4 mm.It can achieve a maximum gain of 9.7 dBi and operates in the frequency band of 5.75～5.83 GHz,with a center frequency of 5.8 GHz.Compared to the average gain of microstrip antennas reported in existing literature,the designed antenna array offers an improvement of 3.87 dB.Finally,the antenna array is fab-ricated and tested,and the test results closely matching the simulations,demonstrating the feasibility and practicality of this design.
