| 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 satisfy the requirement of low side-lobe level and high efficiency in practical engineering.The simulation results show that the designed reflector antenna has high efficiency,low side-lobe level and low profile. |
