Reflectarray Antennas Describes the configuration and principles of a reflectarray antenna, its advantages over other antennas, the history of its development, analysis techniques, practical design procedures, bandwidth issues and wideband technique
微波天线设计的始祖篇,1995年,T. Huynh和K. F. Lee首次提出了U形槽单层贴片微带天线的概念。该天线结构简单,通过在普通矩形贴片天线的贴片上开出U形槽即可得到。由于贴片具有U形缝隙,缝隙边缘流动的电流引入了附加谐振,同时U形缝隙还引入容抗,与探针的感抗相抵消,从而达到了展宽了频带的效果。
