An OAM Patch Antenna Design and Its Array for Higher Order OAM Mode Generation

In this letter, a systematic design procedure is proposed on how to implement the characteristic mode analysis to design and optimize an orbital angular momentum (OAM) antenna with circular polarization. The main idea of this work is by combining proper high-order modes to fit the current distributi...
