Effect of stubs on ferrite microstrip line magnetized to wave propagation

Abstract

Effect on stubs to ferrite microstrip line magnetized to wave propagation was investigated both theory and experiments. Dispersion curve on the line was estimated numerically under parallel plate ferrite transmission line model. Scattering parameters on ferrite microstrip line with stub were also numerically estimated by using HFSS simulator, and proved that wave propagates at negative permeability region of magnetostatic surface wave radiation with left-handed operation.To emphasize interest on effect on stub at strip line, it was developed to coupler and transducers using two lines, and expected their characteristics were observed experimentally.

Split striplines with adjustable parameters and devices based on them

“…There are two main methods to change the parameters of striplines and coupled strip transmission lines. The first method is based on control of dielectric parameters, magnetic or magneto-dielectric medium [1][2][3][4][5]. The second method is based on the introduction of lumped heterogeneities, creating the effect of changing parameters in a limited frequencies range, as this heterogeneity creates a frequency-selective circuit [6].…”

A review on novel magnetic properties of metamaterials CRLH devices : Part 1

“…Over the ferrite CRLH TLs, it has proven that coplanar waveguide based devices needs smaller DC magnetic bias compared to microstrip configuration [7] . Examples for these devices include tunable/nonreciprocal couplers, resonators, circulators, phase shifter [13][14][15][16][17][18][19][20][21][22][23][24][25][26] and antennas [27,28] .…”

“…CRLH ferrite components, such as antennas [20][21][22][23], impedance transformers [24,25], circulator [26], diplexer [27], isolator [28], phase shifter [29], couplers [30][31][32][33] and resonators [34][35][36][37] have been reported.…”
