摘要
文章设计了一款用于微波输能的宽带高增益矩形微带贴片天线,天线的中心频率为2.55GHZ,通过挖槽与增加空气层增加了天线的增益与带宽,介质板选用FR4作为介质材料,接地部分选用铜,介质板的上层固定有辐射贴片,介质板与接地部分之间设有空气层。本设计采用同轴馈电。仿真表明,反射系数相对带宽26.3%中心频率的增益为6.54。
This paper designs a broadband high-gain rectangular microstrip patch antenna for microwave energy transmission.The center frequency of the antenna is 2.55 GHZ.The antenna gain and bandwidth are increased by digging grooves and adding an air layer.As the dielectric material,copper is used for the grounding part,a radiation patch is fixed on the upper layer of the dielectric board,and an air layer is provided between the dielectric board and the grounding part.This design uses coaxial feed.The simulation shows that the reflection coefficient bandwidth 26.3%center frequency gain is 6.54.
