【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。更多还原

【Abstract】 To overcome the limitation of low gain in microstrip antennas and to improve overall antenna 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 fabricated and tested, and the test results closely matching the simulations, demonstrating the feasibility and practicality of this design.更多还原
