On the Phase Shift of a Microstrip Transmission Line Loaded with Magneto-Responsive Conducting Micro-Particles

Abstract

This work demonstrates a novel loading method for a printed microstrip transmission line using variable conductive particle manipulation controlled by magnetic fields. The conductive particle loading showed that the propagation characteristics of the transmission line could be changed, or tuned in the 2 GHz to 3 GHz band. The work presented in this paper is to provide an understanding of the particles' reaction to a measurable magnetic field density and the effect the particles have on the transmission lines propagation characteristics.
