摘　　要：蜂窝通信中采用基于阵列信号处理的自适应天线技术或智能天线技术在移动通信领域引起了广泛的关注。对目前国内外该课题研究现状进行简要述评的基础上 ,对一种新型自适应天线———基于菲涅尔区相位修正结构多波束自适应天线的研究工作进行了概述。基于其性能特点分析 ,结合典型工程应用背景 ,提出了其需要进一步深入研究的理论问题及相关关键技术 ,展示了其良好的工程应用前景。The application of adaptive antennas or smart antennas based on array signal processing techniques to cellular telecommunications has attracted considerable attention. In this paper, a brief account of the current state of the studies on this topic in the world is given, and the research for a novel adaptive antenna with the Fresnel zone phase-correcting focusing configuration is summarized. Based on the analysis of its performance and application setting, some theoretical concerns and key technical matters that need a thorough analysis and study are proposed, and a good prospect of its applications in wireless communications is presented.\;
