Abstract

Circular waveguide to dual-cavity transition is proposed for wideband, high gain, high aperture efficiency and low profile (60.6mm) antenna. Target bandwidth is Ku band downlink and uplink frequency bands. Simulation result shows 40% (10–15GHz) fractional bandwidth at VSWR<1.5. Propose antenna has minimum 11.3 dBi gain at downlink band and minimum 12.4 dBi at uplink band. Aperture efficiency is better than 65% throughout the band. The structure offers a good alternative to standard gain horn antennas but with much less antenna profile. It can be used in phased array applications as well.

用于卫星通信的双腔ku波段天线

针对宽带、高增益、高孔径效率和低轮廓(60.6mm)天线，提出了圆波导向双腔过渡的方案。目标带宽为Ku波段下行和上行频段。仿真结果表明，在VSWR<1.5时，分数带宽为40% (10-15GHz)。建议天线在下行频带增益最小为11.3 dBi，上行频带增益最小为12.4 dBi。整个波段的孔径效率优于65%。这种结构提供了一个很好的替代标准增益喇叭天线，但天线轮廓要小得多。它也可以用于相控阵应用。
