“…It can be seen that the antennas have a negligible effect on the return loss for various bending radius. A similar phenomenon is also observed in the reported antennas [25]. Thus, it can be concluded that the proposed antenna can be used in flexible devices without deteriorating its performance.…”

“…Although the antenna has a compact size of 27 mm × 32 mm with good performance, still it lags in covering complete 5G sub-6-GHzband allocated globally. In literature researchers adopted different techniques including fractal geometries [23], insertion of stubs [24], [25], and so on to achieve wideband. Therefore, to further enhance the bandwidth of the antenna a rectangular stub was introduced at the bottom of patch.…”

A wide-band and tri-band flexible antenna for fifth-generation (5G) sub-6-GHz communication systems is investigated in this paper. The proposed wideband antenna covers the 5G new radio (NR) mid-band, ranging from 2.8 to 5.35 GHz, while the tri-band antenna is resonating at three different allocated frequency bands (2.45 GHz, 3.5 GHz, and 4.7 GHz) for 5G sub-6-GHz communications. This functionality is achieved by introducing hexagonal split-ring resonators in the radiating element, which can be controlled independently without affecting antenna performance to avoid problems of interference in this frequency spectrum. In addition, the antenna also presents a good conformability characteristic, and the simulated results are confirmed with the measurements of the fabricated prototype.

The field of flexible antennas is witnessing an exponential growth due to the demand for wearable devices, Internet of Things (IoT) framework, point of care devices, personalized medicine platform, 5G technology, wireless sensor networks, and communication devices with a smaller form factor to name a few. The choice of non-rigid antennas is application specific and depends on the type of substrate, materials used, processing techniques, antenna performance, and the surrounding environment. There are numerous design innovations, new materials and material properties, intriguing fabrication methods, and niche applications. This review article focuses on the need for flexible antennas, materials, and processes used for fabricating the antennas, various material properties influencing antenna performance, and specific biomedical applications accompanied by the design considerations. After a comprehensive treatment of the above-mentioned topics, the article will focus on inherent challenges and future prospects of flexible antennas. Finally, an insight into the application of flexible antenna on future wireless solutions is discussed.

A low‐profile omnidirectional antenna based on folded Alford loop is proposed for wireless body area network (WBAN) applications in industrial, scientific, and medical (ISM, 2.4‐2.4835 GHz and 5.725‐5.875 GHz) bands. By fabricating two complementary symmetrically folded Alford loops on both sides of a round Roger substrate, the proposed antenna has small volume and omnidirectional radiation capability in both bands. Since the omnidirectional radiation plane is parallel to the human body surface, low specific absorption rate (SAR) can be obtained. The proposed antenna has a profile of 0.639 mm and occupies an area of π × 302 mm2, along with a measured peak gain of 6.1 dBi and 14.1% impedance bandwidth (BW) at 2.45 GHz and peak gain of 2.2 dBi and 6.7% impedance BW at 5.8 GHz. Simulated and measured results reveal that the antenna has good omnidirectional radiation in both bands. Moreover, the bending sensitivity study and SAR analysis prove that it is a good candidate for wearable WBAN devices.
