“…Moreover, the PCB surface wave launcher can be integrated with other RF modules to further improve the performance of the wireless system. Double-fluid-channel design is proposed in contrast to the single channel case [12] investigating the potential improvement over radiation pattern diversity. As the proposed one has more flexibility on two separated channels.…”

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 surfacewave 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.

To enable innovative applications and services, both industry and academia are exploring new technologies for sixth generation (6G) communications. One of the promising candidates is fluid antenna system (FAS). Unlike existing systems, FAS is a novel communication technology where its antenna can freely change its position and shape within a given space. Compared to the traditional systems, this unique capability has the potential of providing higher diversity and interference-free communications. Nevertheless, the performance limits of FAS remain unclear as its system properties are difficult to analyze. To address this, we approximate the outage probability and diversity gain of FAS in closed-form expressions. We then propose a suboptimal FAS with N * ports, where a significant gain can be obtained over FAS with N * − 1 ports whilst FAS with N * + 1 ports only yields marginal improvement over the proposed suboptimal FAS. In this paper, we also provide analytical and simulation results to unfold the key factors that affect the performance of FAS. Limited to systems with one active radio frequency (RF)-chain, we show that the proposed suboptimal FAS outperforms singleantenna (SISO) system and selection combining (SC) system in terms of outage probability. Interestingly, when the given space is λ 2 , the outage probability of the proposed suboptimal FAS with one active RF-chain achieves near to that of the maximal ratio combining (MRC) system with multiple active RF-chains.
