“…Compared with other work, [28] this work renders a relatively large order of magnitude of tan δ µ (approximately 3 × 10 −1 to 5 × 10 −2 ). In addition, this work also found that the value of the imaginary part can be reduced by adding Sm 3+ .…”

The combined effects of Sm3+ substitution together with the addition of 3 wt% Bi2O3 endowed the MgCd ferrites with excellent magnetic permeability and dielectric permittivity. Various concentrations of Sm3+ (x=0.00, 0.03, 0.06, 0.09, 0.12, and 0.15) were employed to modify the permeability (μ') and permittivity (ε') of the MgCd ferrites. XRD, SEM, VSM and vector network analysis techniques were used to characterize the samples. The measurement results reveal that the ferrites processed a saturation magnetization of up to 36.8 emu/g and coercivity of up to 29.2 Oe via the conventional solid-state reaction method. The surface morphology SEM confirms that with increasing Sm3+ concentration, the grain shape changes from a polygon to a circle. Moreover, the outstanding dielectric performance of dielectric permittivity can achieve 23. The excellent properties obtained in Sm3+-substituted Mg ferrites suggest that they could be promising candidates for modern high-frequency antenna substrates or multilayer devices.

“…In order to meet the needs of communication systems, the miniaturization and high frequency enhancement of antennas are receiving tremendous attention from researchers. 1,2 The miniaturization of antennas can be achieved by increasing the permeability and permittivity of the substrate material. In particular, ferrites have a relative permeability and permittivity greater than one, which make them ideal materials for antenna substrates.…”

A series of Ba1.5Sr1.5Co2+xZrxFe24‐2xO41 hexaferrites (x = 0.00, 0.01, 0.03, 0.05, 0.07, and 0.09) were successfully prepared by the conventional solid‐state reaction method. It was found that as the Co2+ and Zr4+ ions entered the hexaferrite structure, the lattice parameters increased, whereas the relative density increased when x = 0.00‐0.03 and then decreased. A suitable amount of substitution increased the DC resistivity, reduced the magnetic and dielectric losses, and made the μ′$\mu ^{\prime}$ and ε′$\varepsilon ^{\prime}$ closer to each other. At x = 0.03, the relative density and DC resistivity of the samples reached their maxim. Besides, both the magnetic and dielectric losses were lowest within the frequency range of 10 MHz‐1 GHz. Meanwhile, the hexaferrite was impedance matched to free space, and the miniaturization factor was about 15. Therefore, this low‐loss ferrite with almost equal permeability and permittivity could be meaningful for antenna miniaturization and high‐frequency applications.

“…Consequently, the assembly of low temperature co-red ceramics (LTCC) with discrete sensors, resistors, and inductors into a single monolithic chip component can achieve multifunctional performance and promote miniaturization in the printed circuit board (PCB) during assembly. [1][2][3][4] For example, Wang et al 5 reported a novel V-modied Li 3 Mg 2 NbO 6 ceramics with outstanding microwave dielectric properties and can reach densication at 900 C. Li et al 6 synthesized the In-doped Mg-Cd ferrite at low sintering temperature using Bi 2 O 3 additive. These efforts make these ceramics promising candidates for LTCC applications.…”
