反射面天线机电场耦合关系式及其应用
On Development and Application of Mechanical-Electromagnetic-Field Coupling Model of Reflector Antennas
摘要
Abstract
Considering surface' s random error and systematic error of reflector antenna, the difference of both errors is discussed by comparing Ruze formula,best-fit paraboloid and mechanical-electromagnetic-field coupling model. Since the deformation error is not concerned in Ruze formula,reflector's precision is required too high sometimes so that the difficulty of antenna' s design and manufacturing is increased considerably. In contrast, the precision of the reflector required by the developed coupling model could be decreased. For the same surface precision, the higher electronic performance could be obtained by the coupling model than by Ruze formula. The experimental results of three antennas respectively are given to demonstrate the difference between them. In addition, the coupling model also paves a road for realization of mechatronics design of reflector antenna in engineering.关键词
