摘要
采用国内首创的新型有机磁性材料做基片 ,提出一种创新设计实现了微带贴片天线的双频工作。这是通过在三角形微带贴片的底边加载矩形凹槽来实现的 ,结构简单且双频比易于调节。由于采用了新型磁性基片 ,使天线尺寸比相同频率的常规贴片天线缩小 ,而具有比常规微带天线宽得多的带宽。文中给出了仿真和实测结果 。
A new organic magnetic material developed in China is adopted as the substrate recently, and a novel design of dual band microstrip patch antenna is proposed, in which the dual frequency operation is realized by loading a rectangular notch at the base of an equilateral triangular patch, resulting in a simple structure and a tunable dual frequency ratio. Due to the new magnetic substrate used, the antenna size is reduced comparied with a regular patch antenna at the same frequency, and much wider bandwidth is achieved. Simulated and experimental results are presented, showing the validity of this design.
