The magnetic current frill excitation model is introduced to simulate the feed structure, thereafter, the properties of coaxially fed microstrip antenna are calculated with additional mode basis functions being introduced to simulate the current distribution at the wire/ patch junction. 最后结合磁流环模型,采用附加模基函数模拟线面结合处的电流分布,计算了同轴线馈电的微带天线的电性能。
Feed network design from the current feed to the voltage feed is discussed in detail, based on the characteristics of different levels of the feed structure and the aims to cut down the coupled effects, the antenna employed current feed. 从电流馈电和电压馈电两个方面分析了馈电网络设计,基于不同层次的馈电结构特点及减少耦合影响考虑,本天线的设计都选取电流馈电。
