摘　　要：介绍了作为反射面天线馈源的宽频带、双极化、恒波束四脊喇叭 ,运用有限元和模式匹配相结合的混合法详细推导且计算了四脊喇叭的广义散射矩阵。然后运用口面积分计算了四脊喇叭的辐射远场 。The quadruple ridged horns having wide bandwidth, dual polarization and constant beamwidth properties and being often used as the feed of reflector antenna operating in an extra wide bandwidth are presented. The generalized scattering matrix of this kind of horn is calculated by using the hybrid method combining the finite element and the mode matching methods, and the far radiated field is computed using the double integral over the aperture. Finally the measured results are given, which are in good agreement with the calculated results.
