摘要:
基于RFID系统对天线的要求,针对单馈电微带天线回波损耗和轴比之间的矛盾,利用理论计算和Ansoft HFSS软件仿真优化的方法设计出了一种用于RFID读写器的新型超高频圆极化微带天线.该天线采用背馈的方法,相对于侧馈有效地减小了天线的尺寸.为实现良好的圆极化性能,该天线利用空气作为介质层.并且采用非对称矩形切角,相对于当前普遍采用的对称等腰直角三角形切角更容易加工和调整. 经过仿真分析得出了各种参数的曲线图,验证了该天线的优越性能.
Abstract:
Based on the requirements of the RFID (radio frequency identity) systems antenna, a new ultrahigh frequency circularly polarized microstrip antenna using in RFID reader was designed aiming at the contradiction between return loss and axial ratio of singlefed microstrip antenna by theoretical calculations and Ansoft HFSS for simulation and optimization. By using the backfeeding pattern, the antenna effectively reduces the size of the antenna relative to sidefeeding. To achieve good circular polarization performance, the antenna uses air as the dielectric layer. Relative to the current widely used symmetric isosceles triangle corner truncated design, the nonsymmetrical rectangular corner truncated design is easier for processing and adjustment. Through simulation analysis, various parameter curves are obtained to verify the superior performance of the antenna.
