In this paper, the protection of a sensitive car-size system using a hemispherical shielding cover is discussed. The shield cover spreads on the soil, inserting some vertical (metal) rods into the ground, and adding a gridded wire carpet under the cover structure. The shielding performance of the cover structure was considered by a numerical simulation and experiments. The proposed cover structure shows the shielding effectiveness (SE) of -40 dB in worst case in the frequency range of 10 to 200 MHz.
