A Study of Installation Location and Mechanism to Suppress Power-Bus Resonance Efficiently Using Lossy Resonator Filters

Abstract

The suppression mechanism of the power-bus resonance using lossy resonator filters at 2.4 GHz for wireless communication was investigated. A full-wave simulation showed that the single and plural filters installed at anti-nodes provided efficient suppression. High suppression can be estimated from the relationship between the driving point impedance at the position where the filter was installed and the input impedance of the filter through analysis focusing on Z-parameters of the power bus. Finally, the suppressing effect could be obtained when the value obtained by adding 10 dB to the magnitude of the driving point impedance at the position where the filter was installed was higher than the input impedance of the filter. The results help in designing the lossy resonator filters.
