Recent Progress in Surface Wave Fluid Antennas

Background: This paper reports the recent progress in using surface wave fluid antennas to improve multiplex gain and outage probability in mobile communications. Surface wave fluid antennas have been recently proposed to solve fading and interference problems in 5 G mobile communications [1], [2]. Theoretical results showed that noticeable improvements can be obtained. In this paper, a channel model verified by extensive simulation and measured results have been developed for optimizing problems in a downlink Fluid Antenna Multiple Access (FAMA) scenario. The single channel fluid antenna reported in [3] is used, its radiation patterns at 21 fluid radiator positions at 26 GHz have been measured and used in the model.
