This paper shows A 2.4GHz two-way directional Antenna of Wi-Fi Systems for Underground Mine-Tunnel. The designed antenna enhances wireless transmission of signals in an underground mine-tunnel in a two-way direction. The research was carried-out…

This paper investigates the effect of interference on Aeronautical Navigation systems by Frequency Modulation (FM) broadcasting signals. Precisely, the paper evaluated the impact of 3rd order intermodulation distortion on the VHF omnidirectional…

Accepted: 4 November 2022 The current global issue of the COVID-19 pandemic has prompted the push and utilization of all available means to halt its spread. COVID-19 is a highly infectious disease, and continuously monitoring early symptoms could…

In the manufacturing industry of Printed Circuit Boards (PCBs), the quality and reliability of circuits are highly dependent on the accuracy of the manufacturing processes. Etching is the most sensitive process needed in manufacturing processes and…

A strong brand is invaluable as the battle for it is high. Nigeria is a country that has been linked with corruption, high unemployment rates, underdevelopment among others. Rebranding Nigeria transforms it into a new brand making it a new haven and…

This paper evaluates HVDS and LVDS concepts by system performance. This is achieved by examining system losses on HV and LV distribution networks in radial AC distribution systems. Challenges associated with system losses may demand network…

Miniaturized monopole planar antennas operating in the VHF/UHF band applied for Digital Video Broadcasting and mobile communication have gained research interest due to their low-profile, compact, and wideband nature. This antenna is capable of…

This study presents an omnidirectional dipole antenna with wideband and low gain variation in the horizontal plane. The antenna is made up of two driven dipoles and two parasitic dipoles placed symmetrically on both sides of a central ground plane.…
