摘　　要：提出了一款工作于2.45 GHz的多向端射增益可调控双模智能阵列天线,可用于隧道通信、雷达探测系统等。该天线阵列由8个相同的平面印刷偶极子和一个环形反射器组成。通过加权功率传输最优化理论计算出天线阵列达到最优增益时所需要的最优分布激励。该天线阵列能够实现水平面全向辐射,全向增益为2.8 dBi,该阵列天线还可以在水平面φ为0°、90°、180°、270°这4个方向产生4个相同的波束,并且每个方向上的增益都可以调控。A dual-mode smart array antenna with adjustable multi-directional end-fire gain that operates at 2.45 GHz is designed,which can be used for tunnel communication,radar detection system,etc.The design consists of a circular ring reflector and eight identical planar printed dipoles.By optimizing the optimal distributed excitation required by the antenna array based on the weighted power transmission efficiency maximization method,the optimal gain of the array is obtained.The antenna array can achieve horizontal plane omnidirectional radiation with an omnidirectional gain of 2.8 dBi.The array antenna can also generate four identical beams in the four directions of the horizontal planeφ=0°,90°,180°and 270°,and each The gain in the direction can be adjusted.
