Radiation Pattern Diversified Single-Fluid-Channel Surface-Wave Antenna for Mobile Communications

In this paper, an antenna design that combines surface wave and fluidic reconflgurable techniques was presented. The antenna operates in a wide frequency range from 23 to 38 GHz, which covers the Very High 5G Frequency band in the US, Europe, China, Japan, and Korea. In this design, only one RF input port is needed to achieve diversity when compared with the conventional multiple RF input ports approaches. From the simulation results, the proposed antenna design could change its radiation pattern based on the position of the fluid radiator. Such radiation pattern diversity feature can deal with channel interference issues.
