“…The sequentially-rotated feed network proposed in [35] was not specifically designed for RF energy harvesting, but its design that consists of seven λ/4 transformers with different characteristic impedances offers a design insight of an efficient feed network for RF energy harvesting. The proposed feed is attached to four 4 × 4 S-shape cluster metasurface as shown in Fig.…”

The desire for battery longevity and ubiquitous wireless charging of mobile devices is driving researchers to explore divergent strategies to extract and harness energy from ambient radio frequency (RF) signals. Different rectenna designs to convert or rectify energy from electromagnetic (EM) signals into direct current (DC) have been explored for wireless power transfer (WPT) and wireless energy harvesting (WEH). However, these rectennas are characterized by low energy capturing and RF-to-DC conversion deficiencies, complex rectifier design, and bulky size. Recently, man-made materials such as metasurfaces with unique EM properties have emerged to address these limitations of existing rectenna systems. This paper presents a comprehensive survey of not only the state-of-the-art advances in metasurface-aided WPT and WEH systems, but also their applications to emerging technologies for future wireless networks such as wireless powered communication network (WPCN), simultaneous wireless information and power transfer (SWIPT), and millimeter wave (mmWave) communication. Besides discussing the research challenges and opportunities, we also present our proposed approach of harnessing metasurface technology to enhance endto-end energy delivery in future wireless networks.

This research proposes a quadruple-cluster leaf-shaped metasurface (MTS)-based circularlypolarized (CP) stacked-patch antenna array with hybrid coupler feed network for sub-6 GHz 5G applications. In the study, the leaf-shaped MTS-based CP stacked-patch antenna is characterized by characteristic mode analysis (CMA). In the antenna design, one cluster of the quadruple-cluster leaf-shaped MTS-based antenna array consists of 4 × 4 leaf-shaped MTS elements; and the hybrid coupler feed network is used to enhance impedance bandwidth (IBW), axial ratio bandwidth (ARBW), and antenna gain. Simulations are carried out and an antenna prototype is fabricated and experiments undertaken. The measured IBW, ARBW, and maximum gain at the center frequency (4 GHz) are 62.5% (3.4 -5.9 GHz), 21% (3.8 -4.54 GHz), and 9.04 dBic at 3.9 GHz. The novelty of this research lies in the use of: (i) the CMA concept to design and develop the leaf-shaped wideband MTS-based stacked-patch antenna with CP radiation pattern; and (ii) a low-complexity hybrid coupler feed network to enhance the IBW, ARBW and gain.INDEX TERMS Antenna arrays, characteristic mode analysis, couplers, metasurfaces, wideband.

“…In modern antennas, metasurface CP patch antennas are deployed in a variety of applications [10], [11], and [12]. The metasurface CP antenna structure typically consists of periodic elements of thin metal sheet in subwavelength and external sources (e.g., microstrip feed line or aperture-coupled feed).…”

In this research, a multi-shaped metasurface broadband circularly polarized (CP) patch antenna with parasitic elements is proposed for 5G new radio (NR) applications. The proposed metasurface CP patch antenna comprises triple-layered substrates without air gap. The upper layer sits with multi-shaped metasurface elements and parasitic patches. The middle layer consists of an L-shaped slot functioning as the ground plane, and the lower layer contains a microstrip and a fan-shaped stub functioning as the feed line. The proposed metasurface CP patch antenna with parasitic elements is evaluated using characteristic mode analysis (CMA). The CMA results indicate that the modal significance of Modes 1 and 2 of the multi-shaped metasurface CP antenna are orthogonal, giving rise to circular polarization. The non-CP radiation of Modes 3 and 4 are suppressed by using the multi-shaped metasurface elements and parasitic patches. The measured impedance bandwidth and axial ratio bandwidth are 42.85% (3.4 -4.9 GHz) and 38% (3.27 -4.6 GHz), achieving the maximum gain of 7.23 dBic at 3.7 GHz. The experiments demonstrate that the multi-shaped metasurface CP patch antenna with parasitic elements is suitable for 5G NR wireless applications. The novelty of this study is attributed to its utilization of multi-shaped metasurface elements and parasitic patches, which effectively suppress non-circularly polarized radiation modes.INDEX TERMS Characteristic mode analysis, impedance, metasurfaces, patch antennas, substrates.
