| Popis: | This paper investigates multi-mode and orbital angular momentum (OAM) mode data transmission techniques by a using a circular antenna array, operating at 28 GHz. The classical mode excitation of the latter is modified such that in the horizontal plane the antenna array operates as multimode transmitter (i.e., it provides broad- , uni- and/or multi-cast transmission), while in the vertical direction OAM transmission occurs: this dual-functionality by a single antenna-array at 28 GHz is presented for the first time. Specifically, it can transmit/receive in either broad-, uni-, multi-cast mode in the horizontal plane and also, it is capable of generating up to 15 spatially orthogonal OAM modes in the vertical direction. The proposed circular array is designed using twelve, low-complexity, multi-layer microstrip patch antennas with high radiation efficiency. It was tested through full electromagnetic analysis in terms of impedance matching, mutual coupling and radiation pattern. It was, also, fabricated and measured: good agreement between simulated and measurement results was observed. The proposed antenna array is perfect candidate for high spectral efficiency data transmission for 5G and beyond wireless applications.
