Design Optimization of Microstrip Antenna with EBG and DGS Using the Genetic Algorithm to Reduce the Mutual Coupling
Abstract: The purpose of this paper is to construct, create, and reproduction of different antenna structures using electromagnetic band gap (EBG) materials and defected ground structures (DGS). Microstrip antennas are processed in order to improve performance by changing the shape of the geometry of the antenna, in particular to reduce the mutual coupling between the elements. The propagation of electromagnetic waves in a specified frequency range have the unique ability to …

Reduction of Mutual Coupling Losses for Dual-frequency Patch Antennas Using Modified Microstrip I-Section
Abstract: AbstractIn this paper, a compact design using modified “I” shaped microstrip section between dual frequency patch antenna array to reduce mutual coupling is presented. Problem of performance degradation of an antenna has to be faced because of mutual coupling. The results of simulation show that coupling reduced from –11.3 to –7.91 dB at 2.40 GHz and from –18.3 to –14.70 dB at 4.5 GHz. Description of antenna design and results …

Advanced 4-Element UWB-MIMO Antenna Design: Achieving High Isolation and Multi-Band Rejection for Advanced Wireless Applications
Abstract: In this study, we present the design, fabrication, and analysis of a step-by-step Ultra-Wideband (UWB) Multi-Input Multi-Output (MIMO) antenna operating from 3 to 14 GHz. The antenna consists of four elements, each characterized by high isolation and equipped with four band-rejection features. These elements are implemented on a Rogers substrate with εr=3. Each antenna element is a modified rectangular patch, incorporating partial ground etching to achieve wider bandwidth. Two sets …

A Review On A Compact Dual Polarized Antenna Array
Abstract: A compact dual-polarized antenna array for low-cost millimeter-wave (mm Wave) applications is proposed in this article. Utilizing a patch antenna with two orthogonal feeds positioned horizontally and vertically, a dual linear polarization antenna can be created. Two ports—a vertical port and a horizontal port—make up the suggested design. The antenna produces horizontal polarization by stimulating the horizontal port. The antenna produces vertical polarization by stimulating vertical port. With the higher …

Modeling of Transformer Windings having Non-uniform Inductance Distribution
Abstract: A direct analytical procedure for analyzing power transformer windings with location-dependent series inductance is presented. This dependence is typically introduced in order to take the inter-turn mutual inductive coupling into consideration. The paper addresses the frequency domain analysis conducted in the complex s- or the jω-domains. Results for the frequency-dependent winding’s input impedance with different treatments of the transformer’s neutral point will be available. The frequency characteristics including the resonance …

Decoding ‘I Do’s and ‘I Don’ts’: Exploring the Surge in Indian Divorce Rates
Abstract: The research explores the evolving dynamics of marriage and divorce in India, highlighting the rise in divorce rates due to increased stress, lack of bonds, and female independence. The study argues that women's financial self-sufficiency has led to a decrease in their willingness to tolerate unsatisfactory or abusive marriages. The research also emphasizes the influence of urbanization, Westernization, and changing attitudes toward marriage as factors contributing to the increase in …
