Abstract
This paper investigates the possibilities of using carbon fiber as an inductor material by analyzing its inductive properties. Various shapes such as rectangular, spiral, helical, and cylindrical line structures have been simulated under various constraints using simulation software. Hardware implementations were also tested and both simulation and hardware results show that carbon fibers have the potential to replace copper inductor lines. The implemented spiral inductor produced a quality factor of 40 while producing an inductance of 4 nH at 1.2 GHz frequency.

Summary
A critical passive circuit element, is extensively used in analog signal processing circuits. With the recent advancement in MEMS technology, the size and performance of inductors have become a major factor in analyzing the efficiency of low-power, high frequency circuits. This calls the need for realization of inductors of very small sizes [1,2,3,4,5]. Carbon fibers are light-weight, corrosion resistant material consisting of fibers about 5 to 10 μm in diameter This analysis queers the disadvantages of copper inductor and provides insights that could potentially open up new applications using carbon fiber
