“…During the embryonic stages of wearable electronics development, it was customary for researchers to persist with copper as the conductive material, which comes at the cost of flexibility. A notable exemplar of this paradigm is evident in textile-based wearable antennas [ 50 , 51 ], which typically employ fabrics, including denim [ 52 , 53 ], cotton [ 54 , 55 ], and flannel [ 56 , 57 , 58 ], as substrates. Such antennas, often referred to as intelligent garments [ 59 ], e-textiles [ 60 ], or smart fabrics [ 61 ], incorporate a thin copper-based conductive layer or conductive fabrics [ 62 , 63 , 64 ] onto these supple fabrics, thereby enabling the integration of wearable electronic functionality.…”

The intersection of biomedicine and radio frequency (RF) engineering has fundamentally transformed self-health monitoring by leveraging soft and wearable electronic devices. This paradigm shift presents a critical challenge, requiring these devices and systems to possess exceptional flexibility, biocompatibility, and functionality. To meet these requirements, traditional electronic systems, such as sensors and antennas made from rigid and bulky materials, must be adapted through material science and schematic design. Notably, in recent years, extensive research efforts have focused on this field, and this review article will concentrate on recent advancements. We will explore the traditional/emerging materials for highly flexible and electrically efficient wearable electronics, followed by systematic designs for improved functionality and performance. Additionally, we will briefly overview several remarkable applications of wearable electronics in biomedical sensing. Finally, we provide an outlook on potential future directions in this developing area.

“…For the proposed FSA, the realized gain is −2.10 dBi at 5.6 GHz and -1.91 dBi at 7.4 GHz represents the antenna eliminates WLAN and X-band signals. Moreover, the gain varies from 2.21 to 3.55 dBi, except at notched bands over operating frequencies of FSA represents the proposed FSA gain is more stable than the reported antennas [22][23][24][25][26][27][28][29][30][31][32][33][34] in Table 3.…”

A compact flower slotted antenna (FSA) for dual band eliminated ultrawideband (UWB) integrated with Ku band applications is proposed. The basic FSA with modified ground structure is utilized for obtaining fractional bandwidth of 137% (3.45-18.45 GHz). The dual band eliminated frequencies are achieved by a via hole to eliminate 5.39 to 5.90 GHz (upper WLAN band) frequencies and by utilizing symmetrical inverted L-shaped parasitic elements to notch 7.30 to 7.75 GHz (downlink of X-band satellite communication link) frequencies. The FSA is having a compact size of 16 × 22 mm 2 printed on low cost FR-4 substrate with two band notched characteristics, nearly omnidirectional radiation characteristics and stable gain over UWB frequency range makes it suitable for portable UWB systems.

“…They should also be able to withstand mechanical stresses and deformations. Various materials have been used as antenna substrates due to their favorable electrical, chemical, and mechanical properties for the human body, including textiles [3], silk [4], nylon [5], leather [6], wash cotton [7], denim [8], polymer, fleece, and paper [9]. In our study, we utilized kapton polyimide with a relative permittivity of 3.5 as the substrate material for the proposed antenna.…”

The proposed paper presents a flexible antenna that is capable of operating in several frequency bands, namely 2.45 GHz, 5.8 GHz, and 8 GHz. The first two frequency bands are frequently utilized in industrial, scientific, and medical (ISM) as well as wireless local area network (WLAN) applications, whereas the third frequency band is associated with X-band applications. The antenna, with dimensions of 52 mm × 40 mm (0.79 λ × 0.61 λ), was designed using a 1.8 mm thick flexible kapton polyimide substrate with a permittivity of 3.5. Using CST Studio Suite, full-wave electromagnetic simulations were conducted, and the proposed design achieved a reflection coefficient below −10 dB for the intended frequency bands. Additionally, the proposed antenna achieves an efficiency value of up to 83% and appropriate values of gain in the desired frequency bands. In order to quantify the specific absorption rate (SAR), simulations were conducted by mounting the proposed antenna on a three-layered phantom. The SAR1g values recorded for the frequency bands of 2.45 GHz, 5.8 GHz, and 8 GHz were 0.34, 1.45, and 1.57 W/Kg respectively. These SAR values were observed to be significantly lower than the 1.6 W/Kg threshold set by the Federal Communication Commission (FCC). Moreover, the performance of the antenna was evaluated by simulating various deformation tests.
