大轴比椭圆波束天线过渡函数的研究

内容简介：研究了不同的过渡函数对椭圆波束天线增益、旁瓣、效率和主反射面轮廓等性能的影响。根据工程应用对低旁瓣和高效率的要求，选取合适的过渡函数，给出了轴比为2：1的椭圆波束天线实例。由仿真结果表明，可以达到高效率、低旁瓣、低剖面的性能。

Abstract：The effect of different transition function on the gain, side-lobe level, efficiency and contour of the main reflector for large axial ratio elliptical beam antenna is ＇studied. A 2 ： 1 axial ratio elliptical beam antenna is given by choosing a proper transition function to level and high efficiency in practical engineering. The simulation satisfy the requirement of low side-lobe results show that the designed reflector antenna has high efficiency, low side-lobe level and low profile.
