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.

“…Therefore, the current distribution will be at the highest magnitude and concentration at the excitation port located at the back of the antenna. Due to this, the current flow will eventually be distributed evenly as it approaches the patch (Samat et. al, 2020).…”

This paper presents a comparative analysis of textile antenna using different feeding techniques for Global Positioning System (GPS-L1) application. Textile materials which are commonly used in the wearable application has gained much attention due to the flexibility and conformability characteristic of the antenna. Nevertheless, the flexibility of this antenna will introduce the bending and stretching element to its physical structure that may degrades the performance. To ensure the maximum power transfer takes place takes place between the source and the antenna, a suitable feeding method must be identified. In this paper, the microstrip feedline technique and coaxial feeding technique will be studied comparatively using Felt textile material as the substrate with the relative permittivity, ?r of 1.098 and tangent loss, ? of 0.0395. It is attached to a copper tape which act as the conductive material with thickness of 0.035 mm. Using Computer Simulation Technology (CST) Microwave Studio software, the result will be analysed comparatively from the performance validation in return loss, gain, bandwidth, directivity and radiation pattern

“…The value of the VSWR should be somewhere between 1 and 2 for the communication to function at its peak level of effectiveness. The lower the value of the VSWR, the more closely the antenna fits the transmission line, which causes more power to be sent to the antenna [23].…”

In the modern world, wireless technology is one way to send information from one place to another. This technology is getting better and better with time, which significantly impacts the activities that make up daily living. This wireless application has the most impact on mobile and other technologies. This research paper shows the design and analysis of a 3.5 GHz microstrip patch antenna (MPA) for wireless applications. The substrate material is Roggers RT/duroid, which has a dielectric permittivity of 2.2 computer simulation technology (CST) software does antenna design and simulation. Some observed parameters are the S-parameter, antenna directivity gain, voltage standing wave ratio (VSWR), and bandwidth. From the simulation, the return loss, VSWR, directivity gain, and bandwidth are -50.4227, 1.0061, 7.43 dBi, and 122.1 MHz respectively. This study aims to find the best return loss, get the most directional gain, and get the VSWR closer to 1. When this antenna was used, the results were better than those in scientific journals and conferences. As a result, this antenna is anticipated to fulfill the requirements of various wireless communication applications effectively.
