摘要
平板端射天线通过优化产生了特殊的组阵规律即天线间距为1.5倍波长的阵列形式,该阵列形式存在栅瓣问题。本文通过提出一种解决栅瓣的途径——正交信号激励的阵列形式,建立了阵列模型,针对阵列模型开展了大量仿真计算,仿真结果证明该阵列形式可以有效抑制栅瓣,实现较低的峰值副瓣电平。
In order to get high directivity,that Plat end-fire antenna is found the space of the array should be increased to be 1.5 wavelengths,but gating lobes are produced.In order to solve gating lobe plat end-fire array antenna drived by orthogonal signals.The array model was given,synthesis pattern of array antenna was analyzed.The computer simulation results confirm the validity of this method.
