摘　　要：设计了一种可用于工程化实际生产的宽带小型化相控阵槽线天线单元,其天线单元采用与半波阵子相结合的槽线天线馈电形式,可工作于400 MHz^900 MHz的带宽之内。天线单元的横向和纵向尺寸只有大约0.2个最低频工作波长,符合天线小型化的需求。仿真结果表明:该天线在2.25倍的工作带宽之内匹配和辐射特性良好,具有体积小、剖面低、频带宽和结构简单等特点,可以作为宽带小型化相控阵天线单元。A kind of compact wide-band phased array slot antenna which can be used in engineering practical production is de- signed. The antenna element uses slot antenna feed which is combined with half-wave days, working within a bandwidth of 400 MHz to 900 MHz. Horizontal and vertical dimensions of the antenna element have only 0.2 most low frequency working wavelength, meet- ing the needs of antenna miniaturization. Seeing from the simulation results, the antenna in 2.25 times bandwidth has good matching and radiation characteristics. The slot antenna with the characteristics of small volume,low profile, wideband, and simple structure, can be used as a compact wideband phased array antenna element.
