PhD Thesis Proposes Advanced Multi-Band MIMO Antenna Design for 5G Mobile Devices

The Department of Electrical Engineering has awarded a PhD degree to Muhannad Youssef Mohsen for his thesis titled Multi-Band MIMO Antenna Design for 5G Mobile Terminals. The research focuses on designing and evaluating multi-band Multiple Input-Multiple Output (MIMO) antennas to meet the demands of next-generation 5G mobile technology.

Comprehensive Performance Evaluation

The study thoroughly examines the performance of the proposed MIMO antenna system by analyzing critical parameters such as:

• Scattering Coefficients: To measure signal loss and reflection.
• Efficiency and Gain: Assessing each antenna element’s effectiveness and strength.
• Radiation Characteristics: Evaluating directional performance and coverage.

Additionally, the research evaluates system-level metrics, including:

• Envelope Correlation Coefficients (ECCs): To assess isolation between antenna elements.
• Diversity Gain (DG): Quantifying the system’s ability to handle multipath propagation.
• Mean Effective Gain (MEG): Measuring average power received across all channels.
• Channel Capacity: Demonstrating the potential for high data throughput.

The results confirm that the four proposed MIMO antenna systems achieve the desired performance, making them highly suitable for future 5G mobile terminals.
