Comparative characteristics of thick film solenoid-bar type inductors

Abstract

As operation frequencies and performance requirements of wireless devices increase, the resultant demands on the performance of passive components also increase. Miniaturization of inductive components for high frequency has been a key research area to address this issue; however, in general, miniaturized thick film inductors can suffer from low quality factors and/or self-resonant frequenciess when compared to their discrete couterparts. The most popular geometries for thick film inductors have been meander types or spiral types, whereas most macro scale inductors are solenoid types. In this research, a modified geometry of a solenoid type inductor is proposed.
