Abstract:

By combining the electric-field integral equation with the moment method,an efficient numericalprocedure for treating the problems of wire antenna with arbitrary shape can be developed. In this paper,the wire antenna with arbitrary shape is analyzed and discussed,and the solution to the current is obtained by using the moment method.Moreover,the exact kernel expressions of Green functions in the integral equation are presented for the solution to the current of wire structure with arbitrary shape.Finally the numerical results and comparisons are perform ed,verifying the efficiency and accuracy of the proposed method.

Key words: electric-field integral equation, wire antenna, moment method, arbitrary shape
