Quasi-Radiator Monopole Antenna
This research focuses on making monopole antennas unidirectional without using cavity backed structures, which is the most common way.
UWB Pattern Diversity Antenna
This research focuses using achieving both broadside and conical beams using a combination of single UWB antennas.
Circularly Polarized Printed Antenna
This research focuses using achieving both broadside and conical beams using a combination of single UWB antennas.
Body Centric Antenna
This research focusses on using monopole antennas specially designed to use radiate unidirectional radiation pattern with cavity backed structures, for on-body applications.
Our Mission
The primary goal of the Antenna Group is to foster active research in antenna design in Ghana. To become the hub of Antenna and Microwave Research in West Africa and the entire continent by designing novel antennas with simulation tools and manufacturing them with the help of local and international partners (that we are currently seeking) for academic research and industry.
