【Abstract】 In this paper,the radiation from a monopole on an elliptic cylinder is discussed by UTD for convex surfaces and two examples are given whose results are consistent with experimental data,which proves UTD to be available. Furthermore,the simplification for the model of elliptic cylinder in engineering application and the factors that affect the radiation pattern are then referred to in this paper.更多还原
