摘要
本文介绍一种适用于微波通信的前馈抛物面新颖宽频带线极化同轴馈源,实践证明该馈源在25%的工作带宽内基本上具有旋转对称的波束(-15dB),且系统VSWR≤1.2,在10%带宽内VSWR≤1.1。因此对用于微波干线上天线VSWR≤1.1指标时,该馈源是很好的选型。
A novel wide-band linear polarization coaxial feed which is suitable forfront end paraboloidal antenna feed of microwave communication system is describedin the paper. It is proved practically that this feed system has the rotated symmetrybeams (--15dB), VSWR≤1.2 in 25% bandwidth and VSWR≤1.1 in 10% band-width. Therefore, this is a good selection for the specification of microwave mainline antenna VSWR≤1.1.
