Electromagnetic Radiation Suppression of Package Lid based on CSRR and Interdigital Structure

In this paper, a novel miniaturized EBG package lid based on the Complementary Split Ring Resonator (CSRR) and the interdigital structure proposed. The proposed novel EBG package lid can effectively suppress the electromagnetic radiation in the specified frequency bandwidth. From the dispersion curve analysis of the unit module and the HFSS simulation of the 3D system, the electromagnetic radiation suppresses using the novel EBG package lid can reach 9.6dB. The simulation result shows the novel EBG structure has good suppression results and can effectively improve the system reliability.
