A Feasibility Study of Circularly Polarized MACKEY Using Sequential Array Technique

This study aimed to convert linear convectional polarization to circular polarization using an unbalanced metasurface-inspired antenna chip developed by the KIT EOE Laboratory (MACKEY). We aimed to achieve a Voltage Standing Wave Ratio (VSWR) of less than three and axial ratio of less than 3 dB in free space and on metal at 2.4-2.5 GHz. For this purpose, we proposed a circularly polarized MACKEY C4 sequential type using sequential array technology. We achieved our goal by optimizing the slit width.
