Congratulations Patrick Nkpeek Tambol

Patrick Nkpeek Tambol is a graduating MPhil student in Telecommunication Engineering at the Kwame Nkrumah University of Science and Technology, Kumasi (KNUST).

His research focuses on the intersection of antenna design, millimetre wave technology, wireless communication, and radio frequency engineering. He aims to contribute to the global push for reliable, high-speed wireless communication through innovative antenna designs and advanced electromagnetic modelling.

As part of his MPhil research, he developed a metasurface-based patch antenna optimised for millimetre wave applications, including 5G and next-generation wireless networks. His work used the metasurface principle in designing the patch by discretising the patch into smaller microelements on the surface of the substrate (like a metasurface) to achieve better impedance matching and performance. The arrangement of the microelements employs a bio-inspired scorpion-shaped patch, achieving a fractional bandwidth of approximately 164% and a peak gain of 13dBi with 93% efficiency. The excitation and simulation of the microelements is done by mutual coupling and induction from the central element. His thesis highlights the potential of compact and high-performance antennas to address the challenges of high propagation losses in millimetre wave environments and the need for compact circuitry in many modern IoT devices.

He credits this success to his commitment to thorough electromagnetic modelling, enjoyment of exploratory antenna design, and excellent support from devoted advisors.  His sincere gratitude goes to Dr Kwame Oteng Gyasi, PhD, his supervisor, Dr Kingsford S. O. Kwakye, PhD, whose guidance has been paramount in realising his research, and Prof. Abdul-Rahman Ahmed, who encouraged and motivated him from the start to the end of this project.

He expresses his immense gratitude to the KNUST Engineering Education Project (KEEP) for financially and resourcefully supporting his academic and research journey financially and resourcefully, and to KEEP management and staff.
