摘要
提出微带全向天线天线,结合微带渐变结构和λg/4短路匹配枝节结构,从而改善了天线的阻抗匹配,降低了天线的电压驻波比,提高了天线的增益。天线实物采用7节微带单元级联,在2 400-2 483.5 MHz的频带范围内实测VSWR〈1.35,天线实测平均增益为9 dB i。采用更多的微带单元级联,可提高天线增益,适用于移动通信基站。
Including the microstrip gradient structure and short-circuit matching structure,the microstrip ominidirectional antenna proposed in this paper improves antenna impedance matching,reduces the antenna＇s voltage standing wave ratio and increases the gain of the antenna.The physical antenna is made of a series of 7 microstrip units.In the frequency range of 2 400-2 483.5 MHz,the measured VSWR is less than 1.35,and the average gain is 9 dBi.Using more cascaded microstrip units can increase the antenna gain.The antenna is suitable for mobile communication base stations.
