A wideband, dual-element MIMO antenna operating in 2.83-7.21GHz frequency bands is presented this study.The proposed design consists of a stub-loaded partial ground plane and stepped feedline with dual circle-shaped radiator on top.The designed operates from 2.83 to 7.21 GHz, covering the C band (4-8 GHz) 5G (sub-6 applications.The peak gain observed 4.8 dBi at 6.2 maximum efficiency 92% 3.2 GHz.The minimum port isolation ECC over 2.83-7.21are as 22 dB 0.003, respectively.To achieve best...
Fractal geometry antennas are much sought after in present scenario of wireless communication due to ever increasing demand for high gain, wide bandwidth, low cost, compact size and easily deployable antennas. An ultrawide band monopole antenna using hexagonal-square shaped fractal is proposed here, which nearly fulfils the above demands. The introduced by iteration square slots hexagonal radiating patch etched on a circular chunk. achieves percentage bandwidth 146% approximately ranging...
This research suggests a compact, wideband Multiple Input Output (MIMO) antenna designed for S-band applications, emphasizing high isolation between closely positioned elements.Achieving this is accomplished through the implementation of Defected Ground Structure (DGS) technique.The DGS realized by etching two elliptical patterns on an economical FR-4 substrate with inherent loss properties.Three rectangular slots and L-shaped stubs are introduced to improve minimize size increment lowering...
