In the fast-evolving realm of communication technology, microstrip patch antennas (MPAs) are in high demand owing to their compact size, lightweight, inexpensive, ease of integration, and compatibility with modern electronic devices. This research focuses on the synthesis of ZnAl2O4Ca (ZAC) ceramic nanoparticles using an economical sol–gel method suitable for microstrip patch antenna applications. The structural analysis study of ZAC nanoparticles confirmed the polycrystalline nature with 8.1 nm of crystallite size whereas an investigation of functional groups showed the corresponding vibration modes. Morphological investigation revealed the spherical grains having their mean diameter of 12.32 nm. The dielectric property’s examination, revealed the dielectric permittivity of 13, loss tangent of 0.02, and conductivity of 67 μΩ−1 cm−1. Furthermore, a prototype patch antenna fabricated using ZAC ceramics demonstrated a dual-band performance at frequencies 2.8 GHz and 4.8 GHz, with return losses of − 25.78 dB and − 28.5 dB, respectively. This work suggests the suitability of ZAC ceramic nanoparticles for use in WLAN applications.

“…Bhongale, S.R., discovered that a Mg-Nd-Cd ferrite substrate resulted in a smaller antenna size and better radiation performance than a standard dielectric substrate [ 5 ]. Ferrite material has been used as the substrate for millimeter wave applications, the antenna size was reduced, and bandwidth increased [ 6 – 9 ].…”

In addressing issues related to electromagnetic interference, the demand for ferrite materials with exceptional magnetic and dielectric properties has escalated recently. In this research, sol-gel auto combustion technique prepared Nickel zinc ferrites substituted with cerium, denoted as Ni0.5Zn0.5Ce0.02Fe1.98O4.X-ray diffraction (XRD), Vibrating Sample Magnetometer (VSM), and Field Emissions Scanning Electron Microscope (FESEM) were used to investigate the structure, magnetic properties, and morphology of Cerium doped NiZn Nano ferrites, respectively. The magnetic and dielectric properties of the sample was examined within a frequency range of 2.5–5.5 GHz. Sample exhibits low permittivity (2.2), high permeability (1.4), low dielectric (0.35) and magnetic loss tangent (-0.5) and highest saturation magnetization measuring 30.28 emu/g. A Novel Double-band, 4x4 MIMO window grill-modeled antennas operating on 3.5 GHz and 4.8 GHz frequency bands for 5G smartphones is designed using the CST microwave studio suite. The performance of window grilled 4x4 MIMO antenna model with Cerium doped NiZn nano ferrites as substrate, is investigated and found the return loss of -35 and -32 dB, with the bandwidth of 200MHz, gain (1.89 & 4.38dBi), envelope correlation coefficient (0.00185), channel capacity loss (0.2bps/Hz), and interterminal isolation of (22& 19dB).The results show that the antenna size is reduced with improved bandwidth, higher isolation and better diversity gain performance using Cerium doped NiZn nano ferrite substrate compared to conventional dielectric substrates.

“…Thus, appropriate μ and ε is necessary. Besides, matching impedances of antenna substrate and propagation medium ought to be seriously regarded to decrease the power loss generating from the reflections 14,15,16,17,18 , which can be realized by obtain approach μ and ε values 19,20,21,22,23 . Meanwhile, low magnetic and dielectric loss is non-negligible for the reason that lower energy loss by heating should be paid attention.…”

The microstructure formation and structural regulation of Mg-Cd ferrites (Cd0.15Mg0.85Fe2O4) with 5% Bi2O3 addition at different sintering temperatures (880, 900, 920, and 940 °C) werer invsetigated for application in VHF antennas. The changes including microstructure, phase composition, magnetic and dielectric properties were mainly characterized. It was found that increasing temperature resulted in superior microstructure with accrescent grain size and denser arrangement. XRD patterns revealed normal spinel phase and a secondary phase of Bi compound. Meanwhile, a reinforcement of the magnetization including increased saturation magnetization (from 37.8 to 46.6 emu/g) and dropped coercivity (from 98.2 to 65.9 Oe) were obtained through hysteresis loops. A slight increment of μ' and ' were measured over a broad frequency range in VHF bands. Therefore, excellent magneto-dielectric properties of the proposed ferrites were obtained. In addition, low magnetic losses (tan δμ ~10 -2) and dielectric losses (tan δμ ~10 -3) indicating low power loss in operation. It is foreseeable that these properties of the proposed ferrites would behave well in miniaturized VHF antennas.
