摘要
提出了1种新的小型化3频单极子微带天线,该微带天线主要由1个横矩形带、2个竖矩形带,2个圆,1个圆环、1个椭圆以及缺陷地组成,可同时工作在蓝牙、射频识别、无线局域网和全球微波无线互联网的通信频段上.为了获得结构的小型化,通过沿微带方向增加1个圆环和1个椭圆来激发出该天线的2个谐振频率,通过改进地板为带圆形和矩形缺陷的拱结构来获得第3个阻抗匹配良好的频段.实测结果显示:该天线在工作频段具有很好的辐射特性和增益.
A new miniaturized triple-frequency monopole microstrip antenna is proposed. The proposed antenna mainly consists of a horizontal rectangular band, two vertical rectangular bands, two circles, a cir- cular ring, an ellipse, and a defected ground plane. The proposed antenna can generate three separate im- pedance bandwidths to cover all the 2.4/5.2/5.8 GHz Bluetooth/WLAN/RFID operating bands and the 2.5/ 3.5/5.5 GHz WiMAX bands. By adding a circular ring and an ellipse along the microstrip direction, the antenna excites two resonant modes and is with miniaturization structure. Because of the introduction of the cambered ground plane with a circular-defect and a rectangular-defect, the third wide band with better impedance matching is obtained. A prototype is experimentally tested, and the measured results show good radiation patterns and enough gains across the operation bands.
