摘要
设计一种在智慧城市背景下,应用于特种设备数据收发装置的窄条式宽带微带贴片天线,利用HFSS对天线进行仿真和优化,该天线实现了-10 dB阻抗带宽90%、-16 dB阻抗带宽56%,有效改善了特种设备收发装置的工作效率;详细讨论了辐射贴片的尺寸以及空气层厚度对天线阻抗带宽和谐振特性的影响规律。最后,通过分析辐射贴片表面电流分布,提出在天线长度方向采用结构反对称的交叉馈电结构,有效改善了偏离主波束角度时的交叉极化。
A narrow-strip broadband microstrip patch antenna is designed for the special equipment data transceiver in the context of smart cities.The antenna is simulated and optimized via the HFSS,achieving a-10 dB impedance bandwidth of 90%and a-16 dB impedance bandwidth of 56%,and effectively improving the working efficiency of the special equipment transceiver.The impact of the size of the radiation patch and the thickness of the air layer on the impedance bandwidth and resonance characteristics of the antenna is emphatically studied.It is proposed to adopt an anti-symmetrical cross-feed structure in the length direction of the antenna by analyzing the current distribution on the surface of the radiation patch,which effectively improves the cross-polarization when deviating from the main beam angle.
