摘要

采用商用现货(COTS)组件设计并实现了一种多用途相控阵天线,工作频率为2.3 GHz,频率范围为2.25 GHz至2.35 GHz。实现了威尔金森功率分配器和移相器的四元矩形微带线性天线阵列,并对其进行了测量。通过对微控制器(Arduino)进行编程,根据预先计算的方程改变移相器的输入电压,从而控制移相器以实现所需的扫描角度。对所选转向角的辐射方向图进行了测量,结果与预先计算的结果一致。

Electronically scanned phased array antenna design and implementation
A multi-purpose phased array antenna is designed and implemented using Commercial Off The Shelf (COTS) components, operating at 2.3 GHz on the frequency range from 2.25 GHz to 2.35 GHz. Four elements rectangular microstrip linear antenna array with Wilkinson power divider and phase shifters was implemented and measured. Controlling of phase shifters to achieve the desired scanning angle is accomplished by programming a microcontroller (Arduino) to change the input voltages of the phase shifters according to pre-calculated equations. The radiation patterns of selected steering angles has been measured and the achieved results were good as the pre-calculated ones.
