Optimization of Performance Parameters of Doped Ferrite-Based Microwave
Absorbers: Their Structural, Tunable Reflection Loss, Bandwidth, and
Input Impedance Characteristics
In this study, M-type barium strontium hexagonal ferrite was prepared
with CoSn doping. The crystallographic structure of ferrite compositions
was explored using X-ray diffraction (XRD). The microwave absorption
characteristics were investigated on a vector network analyzer as a
function of the doping of Co2+ and Sn4+, frequency, and thickness of the
samples. Analysis of measured XRD patterns confirmed the M-phase in the
prepared samples. The electromagnetic parameters accompanied by
permeability/magnetic loss, dielectric constant/loss, were increased
with CoSn content. The obtained results revealed that microwave
absorption was enhanced by doping with Co2+ and Sn4+ ions. The absorption was increased from -15.2 dB in compositions x = 0.0 to -51.09 dB in x = 0.6 composition; -10 dB bandwidth = 2.43 GHz was displayed in x = 1.0 composition at 1.7 mm thickness. Both input impedance and
lambda/4 criterion based on thickness doping govern the mechanism of microwave absorption. x = 1.0 composition owes a large bandwidth to
thickness ratio of 3.52 at the frequency of 10.88 GHz and a percentage
bandwidth of 22.33 % at a thickness of 1.7 mm. The observed absorption
peaks were tuned to the desired frequency by exploiting the composition
thickness and input impedance through doping with Co2+ and Sn4+ ions.
The wide bandwidth with optimized absorption find applications in the
field of wireless communication such as isolators, circulators, and
radar application.
