The antenna is designed using foam substrate with dimension of 33.30*35.96*1.6 mm3 operates from 3.3 to 5.2 GHz, covering 5G sub-6 GHz NR bands N77 (3.3–4.2 GHz), N78 (3.3–3.8 GHz), and N79 (4.4–5 GHz) with a bandwidth (BW) of 1900 MHz and S11of –40.59 dB at 4.45 GHz. SAR analysis, using a three-layer body phantom, measures electromagnetic energy absorption by human tissues over ...

In this paper, a novel metamaterial-inspired microstrip antenna for wireless applications is proposed. The proposed design consists of a radiating path on top and a uniformly distributed split ring-shaped metamaterial structure on the ground. The presented antenna of 50´38 mm with a thickness of 1.6 mm is printed on FR4 substrate and resonates at 1.80 GHz. The design was fabricated ...

In this article we proposed, an extensive investigation of environmentally friendly methods for machining titanium alloy (Ti–6AL–4V), a vital component of the aerospace and biomedical sectors, is presented. The novelty of the proposed work is to improve sustainability by applying various technologies, particularly carbide inserts made by Physical Vapour Deposition (PVD) and ...
