Synthesis and Characterization of Novel Nanoceramic Magnesium Ferrite Material Doped with Samarium and Dysprosium for Designing – Microstrip Patch Antenna

Abstract

The novel nano ceramic magnesium ferrite material doped with double lanthanide i.e., Samarium (Sm) and Dysprosium (Dy) showed the n-type semiconductor, was synthesized by sol-gel technique and sintered in a microwave furnace in order to enhance the electrical and magnetic behavior of this material as per the requirement of Microstrip patch antenna. The structural, surface morphological and chemical compositional properties of this material were investigated by X-ray diffraction (XRD), SEM and E-DAX. E-DAX was used for the quantification of elements (Mg, Dy, Sm and Fe) near the detection limit. XRD and SEM were used for estimation and conformation of nano size of the ceramic ferrite material. The studies of other parameters such as porosity, anisotropy constant, initial permeability, saturation magnetization, DC resistivity, dielectric constant and dissipation loss as a function of Dy-Sm doping concentration and frequency were performed. It was seen that permeability, saturation magnetization, dielectric constant and dissipation loss were found to increase, while DC resistivity was found to decrease with the doping of Dy, Sm ions. The desired properties with extremely low permittivity and low relative loss factor along with an improved DC resistivity was obtained to design and for the studies of a suitable Eshaped micro strip patch antenna(MSPA).

“…There was a noticeable decrease in electrical resistivity for all samples, i.e., by about two orders of magnitude, in the frequency range of 20 Hz–20 MHz. This is in line with results reported in the literature [ 59 , 60 , 61 ].…”

Zinc Aluminate-Based Composite Nanoparticles for Microwave Applications

“…Using this, they fabricated a microstrip patch antenna, which showed a voltage standing wave ratio of 1.66 dB, a gain of 5.73 dB, and an antenna efficiency of 69.82 at a resonant frequency of 14.9 GHz. 8 Wang et al reported the dielectric characteristics of Mg 2 SiO 4 –Li 2 TiO 3 –LiF ceramics with the addition of CaTiO 3 synthesized using the solid-state reaction. They claimed the enhanced quality factor was due to the increased relative density of the prepared composite.…”

“…The fabricated patch antenna showed its resonant frequency of 1.575 GHz with VSWR less than 2. Naidu et al (2012) used the magnesium ferrite doped with double Samarium (Sm) and Dysprosium (Dy) for fabricating the microstrip patch antenna. The efficiency of the patch antenna was noticed to be 69.82 at frequency 14.9 GHz, which its gain of about 5.73 dB.…”
