Radiation simulation on satellite navigation antenna by strong electromagnetic pulse

Abstract

In this paper, a patch antenna of satellite navigation is taken as an example. Using the electromagnetic simulation software CST to design a patch antenna which works in B1 and L1 frequency bands. The antenna is irradiated by different electromagnetic pulse(EMP). The time domain signal waveforms of the antenna output is obtained. Finally, the simulation data are analyzed, and some EMP coupling laws are proposed, which provide some useful conclusions for electromagnetic protection.
