摘要
基于CST软件设计了一种宽带平板天线,在由4个偶极子组成的阵列下方放置一块金属反射板形成定向天线,通过在平板上采用周期结构反射器来扩大天线的带宽,并结合这种方法,设计了工作在760MHz～1220MHz的天线,在此频段内VSWR<2,增益高达10.5dBi。该天线的带宽很宽,且定向性很好,具有广阔的应用前景。
A wide band flat antenna is designed by CST-Microwave Studio.Directional antenna is obtained by putting metal plate under a antenna array which is realized by four dipoles.Periodic structure is used on the metal plate to broaden the bandwidth.A antenna whose bandwidth covers 720 MHz～1 220 MHz（VSWR2）is designed with this method.The antenna with wide bandwidth and strong directional has a wide application prospect.
