Impedance and Q-factor of frequence dependance accoding to ferrites on electrodeless fluorescent lamp

무전극 형광램프의 페라이트 종류에 따른 임피던스 및 Q-Factor의 주파수 의존성

An electric power efficiency of electrodeless fluorescent lamp has big relativie property of gas in lamp, gas pressure, lamp formation, ingredients of magnetic substance and shape and action frequency etc. We used magnetic substance that open self-examination material of electrodeless fluorescent lamp antenna. Ferrite that is used in this experiment was Mn-Zn type. We have examined resistance kind, impedance, Q-factor's frequency characteristic by ferrite. Impedance, resistance and capacitance did not show difference in start frequency 2.65 [MHz] but there was difference quantity. We could know Q-factor's difference according to material, and Q-factor's is important part of antenna design.
