传统的微带贴片天线中的辐射贴片振子都采用矩形(方形)、圆形、三角形、Y形等形状,一般使用单馈法加入微扰激励圆极化波,这里描述的立体式介质埋藏微带贴片八木天线中的辐射贴片振子不同于传统的形状,采用了梅花形辐射贴片振子,并在辐射贴片上开矩形槽,用单点馈电激励圆极化波.仿真结果表明在北斗射频信号S(2.491 GHz±10.23 MHz)的中心频率上,该天线的最大增益为8.72 dB;将梅花形贴片改变成花瓣形贴片后的仿真天线增益增大到8.82 dB,轴比带宽和S11阻抗带宽变宽,为实物天线的制作提供了依据.

The radiation patch vibrator in traditional radiation patch antenna adopted the shapes of rectangle (square), round,triangle and the Y shape. The infinitesimal disturbance is added by using single-feedback method to stimulate the circu-larly-polarized wave. The described radiation patch vibrator in Yagi antenna of spatial dielectric embedded microstrip patch is different from the traditional shapes,which adopts the quincuncial shape,and a rectangular groove is dug on the patch. The cir-cularly-polarized wave is stimulated by single-point feed. The simulation results show that the maximum gain of the antenna is 8.72 dB at the center frequency of BeiDou radio-frequency signal S(2.491 GHz±10.23 MHz). The simulation gain of the anten-na is increased to 8.82 dB by changing the quincuncial patch into the petaling patch,and the bandwidth of axial ratio and S11 impedance becomes wider,which provides the basis for producting the actual antenna.
