Area of Science:

• Wireless communication networks
• Antenna array design
• Telecommunications engineering

Background:

• Current wireless networks struggle to provide reliable service in diverse scenarios, including remote areas, disaster zones, and special events.
• Existing infrastructure often lacks the flexibility and power efficiency needed for rapid deployment and coverage expansion.
• There is a need for innovative solutions to enhance wireless network reach and resilience.

Purpose of the Study:

• To develop and evaluate an energy-efficient, self-backhauled base station system for improved wireless connectivity.
• To explore the use of multi-active/multi-passive parasitic antenna arrays (MAMPs) for wireless backhaul and fronthaul links.
• To address connectivity gaps in challenging and underserved environments.

Main Methods:

• Utilized drone-mounted portable access points (PAPs) for flexible network deployment.
• Implemented multi-active/multi-passive parasitic antenna arrays (MAMPs) for wireless backhaul and fronthaul.
• Focused on energy efficiency and reduced hardware complexity through MAMP design.
• Tuned parasitic element load values to achieve directional beamforming.

Main Results:

• MAMPs offer increased range and signal strength with reduced hardware complexity and power consumption.
• The system achieves performance comparable to traditional Multiple Input, Multiple Output (MIMO) and phased array systems.
• Directional beams with high gain and narrow beamwidth are achievable by adjusting parasitic element loads.
• The MAMP design ensures favorable radiation properties.

Conclusions:

• Drone-mounted PAPs with MAMPs provide a viable solution for extending wireless network coverage.
• MAMP antenna technology offers a cost-effective and power-efficient alternative to conventional antenna systems.
• The proposed system enhances wireless network resilience and accessibility in difficult-to-reach areas.
