摘　　要：针对一体化天线的需求,本文提出1种覆盖L、S、X、Ka频段的多频段天线馈源。通过将L/S宽带振子与X/Ka同轴喇叭有效组合,使得馈源在L、S、X、Ka各频段带宽范围内具有良好的阻抗匹配性能及基本一致的辐射性能。通过L/S和差网络和X、Ka频段TE21模跟踪器,使馈源在S、X、Ka频段具有单脉冲自跟踪功能。经过仿真和实测可知,该四频段馈源作为反射面天线的馈源,在工作频段内具有优异的电性能。In order to meet the demands of integrated antenna,this paper presents the design of a multiband feed which covers L、S、X and Ka band.By effectively integrating wideband dipole antenna at L、S band and coaxial horn at X、Ka band,the feed has a good impedance matching performance and consistent radiation characteristic at L、S、X and Ka band.It's a monopulse feed with self-tracking function at S、X and Ka band,because it has sum-difference networks at L、S band and TE21 mode trackers at X、Ka band.The simulation and measured results show that,the feed possesses excellent performance at the working band as the feed of reflector antenna.
