چکیده
In this paper, an Archimedean spiral antenna has been developed to flexibly radiate orbital angular momentum (OAM) wave with tunable modes. The operation mechanism for generation of the OAM is elaborated in terms phases currents flowing on arm structure. Two pairs feeding probes are introduced excite antenna. With signals different phase differences fed into antenna, waves modes $l=\pm 1$ , 2$ and their all mixed radiated, respectively. Simulated measured results given demonstrate that proposed radiates from sole mode four overlapped band 5~6 GHz.

متن کاملTravelling Wave Mechanism and Novel Analysis of the Planar Archimedean Spiral Antenna in Free Space
While Archimedean spiral antennas were invented a half-century ago, only selfcomplementary impedance can be evaluated directly from the Babinet’s principle. This paper examines the effects of metal width and arm spacing on printed spiral’s input impedance. A model is proposed based on examination by decomposition of planar spiral. A closed-form expression for the input impedance of Archimedean ...
