What is it about?
A meta-element is designed to control the surface phase of a grounded substrate and reflect efficiently. Based on the element, a Quasi-Sierpinski distribution is made over the surface in which the phased varies in a clockwise manner. A microstrip antenna radiates a quasi-spherical beam towards the surface and the surface reflects a OAM beam with fundamental mode.

Communication channel capacity improvement Mode division multiplexing low profile planar low cost structure
Perspectives
Designing and analyzing this antenna was exciting for me as a main author. As a growing field, OAM based antennas are interesting to work on. There are a lot to investigate further.
