Abstract(in Japanese) (See Japanese page)
Abstract(in English) A four-value multiplexing orbital angular momentum (OAM) communication scheme is proposed using loop antenna arrays. Considering the radiated fields of loop antennas, MIMO communication without signal processing is shown to be realized by controlling the current distribution. Through numerical analysis on the current with the generalized Z-matrices, a single expansion-coefficient for the current distribution is shown to be dominant, where the loop perimeter is approximately the integral multiple of the wavelength. A loop antenna with a reflector improves the uniqueness. Arrays of the antennas are shown to be effective for short-range OAM communication. For long-range OAM communication, a configuration to collimate the radiated fields with paraboloids is proposed and analyzed, which is shown to be effective for long-range OAM communication. The measured transmission isolation is more than 12 dB for a 1-cm short-range OAM communication, and the simulated transmission isolation is more than 10.9 dB for 1-m long-range communication.
