Abstract
An infinitesimal dipole modeling (IDM)-based analysis method is proposed to calculate the coupling coefficient (CC) between two uniform circular array (UCA)-orbital angular momentum (OAM) antennas. The proposed method is demonstrated to be more accurate than the asymptotic expression while also being more computationally efficient compared to the method of moments (MoM)-based full-wave simulation. Moreover, the proposed method enables CC analysis between UCAs operating in different OAM modes or in the presence of misalignment. The proposed method can potentially be utilized to estimate channel coefficients electromagnetically and to design OAM communication systems.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
