“…When compared to other conductive material, Copper tape with a thickness of 0.035mm is frequently utilized in wearable antenna due to its cost effectiveness [10][11][12]. Textile material plays a major role in wearable antennas to employ in radiating part which has low conductivity and provides more flexibility [35] [101]. The usage of conductive fabrics and ink applies to many opportunistic innovations for a wide variety of wearable devices in the field of biomedical application.…”

“…Surface waves are suppressed due to the presence of reflected EM radiation between the radiator and ground area of the J-slot EBG. This effect makes an antenna to lower the back radiation up to 0.85 W/Kg and average gain of 2.44 dB at 2.45 GHz [35]. A Patch antenna designed with reactive impedance surface (RIS) operates at 2.45 GHz resonant frequency with the usage of felt substrate and conductive part as ShieldIt for better flexibility.…”

In recent years, wearable antenna demand in biomedical applications has increased drastically. Several effective techniques and efficient structures of antenna were proposed to overcome the challenges with respect to the vicinity of the human body. In this paper, substrate and conductive material for the wearable antenna are reviewed thoroughly to ensure that it operates consistently and with flexibility. The design of wearable antennas becomes challenging when flexible substrates are examined, better conductive materials are employed during manufacturing processes and the issue exists in body-worn implementation.To address these issues in this paper, exhaustive literature is carried out based on validated characteristics such as Specific Absorption Rate (SAR), gain, and bandwidth by employing radiating structure, feed, ground, and slot optimization. Effective topologies for gain enhancement, bandwidth enhancement, and SAR reduction for various wearable antenna designs on biomedical applications were reviewed through qualitative study. This extensive study on flexible and wearable technology explores the various problems and challenges involved while designing suitable antennas are discussed. This review paper also highlights the advancements in 5G technology, applications on ISM band and IOT, with particular emphasis on wearable antennas and their potential applications in the biomedical field.INDEX TERMS Wearable antenna, SAR reduction, gain enhancement and bandwidth enhancement.

“…Therefore, to make it more practical, flexible and suitable to be worn, a study on fabric material for antenna substrate such as felt, cotton, jeans, and polyester is done [8][9][10]. Many studies related to textile antennas such as materials and types of patch used [11][12][13], sewing and embroidery effects [14,15], Electro-Textile [16,17], water and moisture effects [18], specific absorption rate (SAR) by human [19,20], bending effects [21,22] and simulation of actual fabric [23] is developed in order to enhance the technology.…”

In this paper, three antennas with different designs, which are square, circle and edgy patch (flower) were simulated and fabricated. The experiment was carried out to study the effects of bending on these three different shapes of antennas. Two bending conditions which are H-plane and E-plane were used. The antenna was designed to resonate at 1.575 GHz for GPS application and to be incorporated with human arm. Thus, the bending angle was specified to be 135o which is about the size of a typical human arm. As the paper focusing on the bending effects only, the characteristic of the bending structure was set to be equal to the air, with Ɛr=1. The antenna characteristics such as gain, resonant frequency and radiation pattern were analyzed for these three shapes of antennas. As a result, the shape of the radiating patch has significant impact on the antenna performance under bending conditions. Based on the comparison of E-plane and H-plane data, the edgy shape was found to be more affected in term of gain performance as compared to other shapes. Bending on E-plane has shown severe degradation in antenna gain performance, whereby at H-plane, significant improvement in gain was observed
