AB  - In this work, composites of M-type Ba(1-x)SrxFe12O19 hexagonal ferrite (x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) and paraffin wax have been prepared. Microwave characterization of the prepared composites was performed with a vector network analyzer from 0.13 GHz to 3 GHz. The dependence of Sr2+ ion content on different compositions was determined in terms of grain morphology, dielectric, magnetic, conductivity, and reflection loss (RL) properties. The grain size varied with dopants and rendered a significant effect on material parameters. The dielectric and magnetic loss tangent were reduced with the increase in frequency and content of Sr2+ ions. The AC conductivity followed the trend of gradual increase with frequency and x=1.0 composition attained the lowest value encompassing the frequency spectrum mostly. The observed RL peaks have been narrow in Ba0.8Sr0.2Fe12O19/wax composite and broad in SrFe12O19/wax composite along with the low frequency spectrum. x=0.6 composition has-0.35x10(-3) dB reflection loss at 0.15 GHz. All compositions revealed more than 99.77% unattenuated (low-loss) microwave signal, with -0.01 dB bandwidth >= 1.50 GHz, and owe good scope for their application in low-loss microwave devices.

AB  - The microwave characteristics of composites prepared from Ba0.5Sr0.5CoxTixFe(12-2x)O19/paraffin wax with 10% and 20% volume fraction of ferrite powder in wax have been examined in the test frequency range of 0.13-4 GHz. The purpose was to determine an optimum composition that could be used in the design of microwave devices for low loss wireless communication. The effect of volume fraction, doping, and thickness on dielectric, magnetic, conductivity, and reflection loss characteristics was explored to ascertain microwave low loss/unattenuated transmission. The results reveal that the dielectric and magnetic properties can be tuned by Co(2+)and Ti(4+)ion doping and the percentage volume fraction ratio of the ferrite in the ferrite/wax composite. The height of reflection loss dips increased with thickness and they narrowed for higher doping with Co(2+)and Ti(4+)ions. All compositions render 98.8% unattenuated transmission of the microwave signal encompassing the majority of the investigated frequency regime. Compositionx = 0.6 has the maximum reflection loss of - 0.35 x 10(-3) dB at 0.15 GHz. The obtained results for these compositions could be considered for designing microwave devices for low loss wireless communication with 0.05 dB bandwidth of 3 GHz in the explored microwave range.
