摘　　要：论述了一种用于智能天线系统的新型圆形天线阵列与校正网络的设计方法。设计了一种具有良好一致性和高增益全向特性的新型直排印刷振子天线结构,并采用奇偶模分析方法,实现了一种18威尔金森功分器/合路器与平行耦合线定向耦合器相结合的校正网络。实验结果证明,研究结果对于3G通信具有很高的实用价值。A novel design procedure of a circular antenna array and its calibration technique for smart antenna system is proposed. Firstly, a novel omni-directional high-gain collinear printed dipole structure is presented. Then, a calibration net-work comprised of a 1..8 Wilkinson power divider/combiner and coupled line directional couplers is analyzed by even and odd mode method. Experimental results show that the design procedure is of high value for the 3^rd generation mobile communication.
