“…The Microstrip Patch Antenna (MSPA) emerges as a favorable choice for wearable devices and GPS applications due to its flexibility, light weight, low cost, ease of fabrication and integration, and low-profile nature [3]. However, these antennas tend to have high back-lobe radiations, thereby raising concerns about body absorption of this radiation [4].…”

Fulfilling the requirements of 5G applications necessitates the design of low-cost, compact, and high-performance antennas capable of supporting high data rates. As these antennas are often in direct contact with the human body, it is imperative to limit radiation exposure. This study presents the design of a Microstrip Patch Antenna (MSPA) with a resonant frequency of 28 GHz. The performance of the proposed design is evaluated using Computer Simulation Technology (CST) software. Considering the importance of compactness in 5G applications, the dimensions of the proposed antenna have been optimized for this purpose. This paper also discusses the role of the ground plane in reducing the Specific Absorption Rate (SAR). The proposed MSPA design demonstrates a high gain of 7.3 dB, a radiation efficiency of 89.4%, and compact dimensions of 5.18×3.36×0.3 mm. The maximum SAR value is 1.68 W/kg (per 1 g of tissue), or 0.121 W/kg (per 10 g of tissue). These results suggest that the proposed design holds promising potential for enabling low-cost, compact, high-speed 5G devices that are safe for human tissues. This is particularly relevant for wearable devices, the Internet of Things (IoT), and mobile wireless networks.

“…However, it has certain limitations, such as low gain, reduced efficiency, narrow bandwidth, spurious radiation, and out-of-phase reflections [ 3 ]. Such worn antennas with high back-lobe radiations may cause increased electromagnetic absorptions when placed close to the body [ 4 ]. To overcome these limitations, metamaterial surfaces or artificial ground planes can serve as an alternative.…”

This paper presents the performance comparison of a dual-band conventional antenna with a split-ring resonator (SRR)- and electromagnetic bandgap (EBG)-based dual-band design operating at 2.4 GHz and 5.4 GHz. The compactness and dual-frequency operation in the legacy Wi-Fi range of this design make it highly favorable for wearable sensor network-based Internet of Things (IoT) applications. Considering the current need for wearable antennas, wash cotton (with a relative permittivity of 1.51) is used as a substrate material for both conventional and metamaterial-based antennas. The radiation characteristics of the conventional antenna are compared with the EBG and SRR ground planes-based antennas in terms of return loss, gain, and efficiency. It is found that the SRR-based antenna is more efficient in terms of gain and surface wave suppression as well as more compact in comparison with its two counterparts. The compared results are found to be based on two distinct frequency ranges, namely, 2.4 GHz and 5.4 GHz. The suggested SRR-based antenna exhibits improved performance at 5.4 GHz, with gains of 7.39 dbi, bandwidths of 374 MHz, total efficiencies of 64.7%, and HPBWs of 43.2 degrees. The measurements made in bent condition are 6.22 db, 313 MHz, 52.45%, and 22.3 degrees, respectively. The three considered antennas (conventional, EBG-based, and SRR-based) are designed with a compact size to be well-suited for biomedical sensors, and specific absorption rate (SAR) analysis is performed to ensure user safety. In addition, the performance of the proposed antenna under bending conditions is also considered to present a realistic approach for a practical antenna design.

“…AMC is one type of the metamaterial. Studies on the use of AMCs to lower the coupling effect between the antenna and human body were proposed by researchers [11][12][13][14]. Owing to the special reflective phase characteristics of AMCs, the radiation from the back lobes was decreased and the SAR value of the antennas towards the human was reduced; at the same time the radiation from the front lobes and the antenna gain were enhanced.…”

The wearable textile antenna plays a decisive role in the currently increasingly wireless communication network area. To realize the miniaturization and electromagnetic reliability, a slotted full-textile microstrip antenna was designed and fabricated using the screen printing method. The measured return loss and radiation pattern were tested and compared with the simulated results. Additionally, the adhesion between the silver paste coating as the radiation element and the textile substrate was detected using sticking tape as well as observation by the microscope. To develop the designed antenna in the on-body application, the artificial magnetic conductor (AMC) was designed, optimized and fabricated. The antenna performance results showed that the existence of the AMC had a significant effect in reducing the body coupling and antenna backward radiation.
