摘要
平面宽缝天线具有全向辐射,中等增益等特点,是最具吸引力的平面宽带候选天线之一。平面宽缝天线具有不同的缝隙形状,如矩形,圆形,弧形;具有不同的馈电形状,如T形,十字形,叉状,蝴蝶结形,星形枝节,π形,双T形,圆形,矩形等。仿真和设计了一款带圆柄的微带线馈电的宽带圆形缝隙天线,并通过添加带多调谐结构的反射背腔使天线获得了良好的单向辐射的辐射特性。
Planar wide-slot antenna is one kind of the most attractive broadband planar antennas,because of its characteristics of omni-directional radiation and moderate gain.The slot shapes of planar wide-slot antennas are having great variety,such as rectangular,circular,curved.The antenna also has different shapes of the feed,such as T-shaped,cross-shaped,bow-shaped,π shaped,double T-shaped,round shaped,rectangular and so on.This paper simulated and designed a wide-band microstrip circle-slot antenna.By adding tuning-chips into the reflected cavity,the antenna obtained perfect unidirectional performance.
