Abstract :
The Time-Domain Integration Equation (TDIE) is used to solve the radiation and scattering problems of thin-wire antenna and array. To solve the integral equation by the method of moments, the triangle impulse function and quadratic spline function are respectively selected as basis functions in spatial domain and time domain. To characterize the effects of the load on the scattering fields, an equivalent circuit method and a loaded TDIE method are developed, and they are proved to be coincident. Numerical results for a dipole antenna and a Yagi-Uda antenna are presented.
