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

In this paper, we present an antenna design for millimeter wave 5G applications. The proposed antenna has a wide working frequency range from 23.5 GHz to 36.5 GHz. This can cover the millimeter wave 5G frequency band in most countries. The design is simple and will mitigate the difficulty when implementing in a wireless system with reconfigurable capability. The antenna design only needs a single RF port as input to achieve radiation pattern diversity by moving the fluid radiators in its two channels. With the radiation pattern diversity capability, the problem like weak signal strength and inter channel interference can be eased.The design shows higher dynamic range of patterns turning when compare to the previous work on single-channel surface-wave antenna with the purpose of wider angular coverage with multichannel design. The comparison result of the two designs will also be provided in this paper.
