Orbital Angular Momentum (OAM) Antennas via Mode Combining and Canceling in Near-field
Abstract Orbital angular momentum (OAM) mode combining and canceling in the near-field was investigated using a Cassegrain dual-reflectarray antenna composed of multiple microstrip patches on the main and sub-reflectarrays. Microstrip patches on dielectric substrates were designed to radiate the par...
