Abstract
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 through scientific design and simulation-using high frequency structure simulator (HFSS). This antenna has fabricated and tested. The antenna is in the shape of a rectangle, partitioned into 12 sub-rectangular rings hooked together, that work in a standing-wave mode. The high-gain two-way radiation property realized by the currents distribution in-phase on the vertical edges. The dimensions of the desired ring are 230 mm, 22 mm and 0.8 mm $(1.84\lambda, 0.17\lambda $ and $ 0.006\lambda $ at 2.4 GHz). The simulated and measured -10-dB bandwidth is about 340 MHz (2.320–2.66 GHz), the simulated peak gain is 8.4 dBi. Presentation and discussion of the simulated results showed that the proposed antenna in two-way direction application is of high directional radiation gain, low profile and easy to build.
