This paper reports a 60-GHz radial line slot antenna (RLSA) for non-far region orbital angular momentum (OAM) multiplexing. An OAM beam-switching circuit that underneath the RLSA, is used for feeding the RLSA through four open posts. The OAM beam-switching circuit is based on a post-wall waveguide. A Gaussian beam has been launched by applying a Gaussian amplitude taper and a convex-lens phase taper on the antenna aperture. The simulated results show that, at the design frequency, the proposed antenna can generate three OAM-mode states: l = 0, -1 and +1 with good spatial distributions. |
