- Abstract
This paper presents an efficient hybrid method consisting of nonuniform mesh finitedifference- time-domain (FDTD) method, thin wire model, and transmission line (TL) equations method, which is utilized to analyze transient responses of the microstrip patch antenna loaded on a vehicle platform illuminated by a high-power electromagnetic pulse (EMP). This hybrid method avoids overfine mesh generation, thereby improving the computational efficiency and saving the computational memory. The accuracy and efficiency of this method are verified by comparing with the simulation results of traditional FDTD and computer simulation technology microwave studio (CST MWS). Then, considering the influence of the incident conditions of EMP and the support structure of antenna on the coupling effects of the antenna, the coupling responses of the 1.575GHz microstrip antenna are discussed in terms of incident angles of EMP, heights of the support structure, top areas of the support structure, and different positions of the support structure on the platform. The obtained changing regularity of the transient responses is useful for further designing the installation structure of the antenna and electromagnetic protection against the external EMP.
