The performance sensitivities to the geometric parameters in fabrications are examined to estimate the manufacturing uncertainty. We consider randomly nonuniform thicknesses of a conductive ink and the two sandwiching dielectric substrate layers on both sides to fabricate PCAAs. The EM absorbing capability is studied on the S-parameters (the reflection and transmission coefficients) and the resulting power efficiency, using numerical HFSS full-wave simulations at a frequency band of 10 GHz. Experiments on prototype samples are also conducted. They showed that a fabrication accuracy of better than 10-4λ is required to assure a stable performance. ? 2021 IEEE. |
