【摘要】 设计了一种工作于UHF波段的宽波束相控阵天线单元。通过伞状印刷对称振子加载金属背腔的方式,实现了天线的水平面波束较宽、垂直面波束较窄的增益空域覆盖特性。天线带内实测驻波小于1.75,实测增益大于6.1 d B。更多还原

【Abstract】 A wide-beam phased array antenna element operating at UHF band is designed. The air coverage characteristics of wide beam in the horizontal plane and narrow beam in the vertical plane are realized through the umbrella printed dipoles with the metal back cavity. The test results indicate that the VSWR and the gain of the antenna are less than 1. 75 and greater than 6. 1 d B respectively in the operating band.更多还原
