An Investigation of Unloaded Quality Factor of λ/2 and λ/4 Resonators

摘要

This paper proposes an investigation of Q_0 of λ/2 and A/4 resonators with respect to electric current density flowed on resonator. The assumption of decreased Q_0 of λ/4 resonator has been proved at this time. In our study, it is found that Q_0 of λ/4 resonator (120) is decreased, due to a loss of electric current density occurred through a short circuit of via-holes made at the end, which is lower than that of λ/2 resonator (150).
