Area of Science:

  • Electrical Engineering
  • Antenna Theory
  • Wireless Communications

Background:

  • Growing demand for reliable wireless connectivity in tunnels for users and critical networks.
  • Existing wireless solutions face challenges with elongated coverage and signal obstruction in tunnel environments.

Purpose of the Study:

  • To develop a low-profile, bidirectional antenna array for efficient wireless communication in tunnels.
  • To address challenges of coverage and signal integrity in underground wireless networks.

Main Methods:

  • Design and implementation of a low-profile bidirectional antenna with dual-magnetic-current mode.
  • Configuration of a sparse planar array of eight antennas to minimize mutual coupling and grating lobes.
  • Demonstration of adaptive beamforming for single or multiple directional beams.

Main Results:

  • The bidirectional antenna exhibits radiation patterns with 3-dB beamwidth coverage at near-end-fire angles.
  • The antenna array achieves scanning gains of 11-15 dB in near-end-fire directions.
  • Adaptive beam generation demonstrated for user-centric communication.

Conclusions:

  • The proposed antenna array effectively overcomes wireless coverage limitations in tunnels.
  • The system supports intelligent communication with low power consumption and high bandwidth.
  • This technology is suitable for enhancing internet access, sensor networks, and control systems in tunnel environments.
