主 题：Antenna array bandwidth beam steering orbital angular momentum
摘 要：Orbital Angular Momentum(OAM)is an intrinsic feature of electromagnetic waves which has recently found many applications in several areas in radio and *** this paper,we use OAM wave characteristics to present a simple method for beam steering over both elevation and azimuth *** design overcomes some limitations of traditional steering methods,such as limited dynamic range of steering,the design complexity,bulky size of the steering structure,the limited bandwidth of operation,and low *** on OAM wave characteristics,the proposed steering method avoids design complexities by adopting a simple method for generating the OAM-carrying *** waves are generated by an array of Planar Circular Dipole(PCD)*** elements are designed to cover a wide bandwidth range between 3 and 30 *** transmitting array shows an enhanced gain value from 8.5 dBi to almost 11.5 dBi at the broadside *** the enhanced PCD-based OAM generation,the novelty of the design lies in a new method of beam *** steering is then performed by controlling the electrical feeding of the PCD elements;the beam azimuthal location is managed by turning off some of the PCD elements,while the elevation is determined by changing the gradient phase of excitation for the turned-on PCD *** analysis of the steering method is carried out by finding the mathematical model of the system and the generated *** performance has been verified through numerical simulators.
