We address the question of robustness of damaged microstrip antennas, the damage being either penetrating, caused by fragment impact, or floating, caused by manufacturing imperfections. A simple analytic expression is derived to facilitate the prediction of robustness. To verify this expression a Monte Carlo method, based on a general 3D electromagnetic solver, is used to evaluate the robustness of the antennas. The simulations are verified by measurements and supplementary simulations in an alter- native electromagnetic solver, using the finite difference time do- main method (FDTD). The agreement between the simulated results and the analytic expression is found to be good in a qualitative comparison. [ABSTRACT FROM AUTHOR]
