- Examining the comparison, the improvement is found at the resonance frequencies of the original one feed structure to the reduced RE level introduced by the two freed system.
- Fourth, slit-loading in the rectangular power/ground planes is included to see the validity of the derived expression. Finally, the vector fitting technique is adopted to verify the calculated and measured results with building up an equivalent model.
- This paper suggests the followings. First, a novel single sum expression is derived to calculate the fields and impedance of the power/ground planes with arbitrary loads. Second, the use of the proposed method on the decoupling capacitor(DeCap) loaded structure shows the effectiveness in RE reduction.
- The radiated emission from the power/ground planes is estimated by a new single modal sum expression derived to calculate the field and impedance as well as resonance properties of the structure with arbitrary lumped loads. It could reduce computation time by 1/100 or less from the conventional method, with the same accuracy.
- It could reduce computation time by 1/100 or less from the conventional method, with the same accuracy. Using the proposed method, the resonance problems of the power/ ground planes could be improved by adopting a DeCap, a slit and the differential feeding technique. This way of resonance-damping was confirmed to effectively lower the RE levels at the original resonance modes through experiments.
