High Frequency Characteristics Of Ferrite Materials And Applications To Microstrip Circuits
Abstract
Dispersion behavior of the parameters of microstrip lines printed on ferrite substrate is presented. The characteristic impedance for lines on magnetized ferrite substrates are obtained for partially magnetized substrates in the direction of wave propagation and vertically magnetized substrates with variable DC magnetic field. The obtained results are applied to analyze variable phase shifters, controlled resonators, and impedance matching.
