短路针加载微带贴片天线结构复杂,特性受多种因素影响,且不易实验调试,因此设计这种天线非常困难.为了解决这一问题,提出了短路针加载微带贴片天线的优化设计方法.该优化设计方法共分两步进行,首先,对天线的频率特性进行优化,然后在此基础上对天线的阻抗特性进行优化.利用该法,对工作于移动通信频段的短路针加载矩形贴片天线进行了具体设计,设计结果表明,利用该法进行设计,不仅可以得到同时满足频率特性和阻抗特性的设计结果,而且设计的收敛性也大大提高.
The structure of the microstrip patch antenna with short pin loading is complex and its characteristics are affected by many factors and it is not easy to experiment and debug.Therefore, it is very difficult to design this kind of antenna.To solve this problem, an optimized design of microstrip patch antenna The optimization method is divided into two steps: Firstly, the frequency characteristics of the antenna are optimized, and then the impedance characteristics of the antenna are optimized on the basis of this method.With this method, the short circuit pin working in the mobile communication band is loaded with rectangle The design of the patch antenna is carried out. The design results show that the design of the patch antenna not only meets the design requirements of both the frequency and impedance characteristics, but also greatly improves the convergence of the design.
