“…İn the literature, there are a lot of work about electromagnetic field changes of antenna structures. Especially, electric field changes are important, because the biggest difference is of electric field values (Asif, Hansen, Iftikhar, Ewert, & Braaten, 2019;Bao, 2019;Khan, Razzaq, Iqbal, Qamar, & Zubair, 2018;Ma, Sydanheimo, Ukkonen, & Bjorninen, 2018;Nesasudha & Fairy, 2018;Paracha et al, 2019;Rong, Leeson, Higgins, & Lu, 2018;Zamani, Ahdi Rezaeieh, Bialkowski, & Abbosh, 2018).

Cancer diseases significantly affect lives of many people for last years. The diagnosis and treatment process is quite difficult and painful. It is especially important to reach the result of pathological tissue samples in which the structure of the cancerous tissue is determined and helps to shape the treatment in a short time. Today, it may take days or even months to obtain these results. In this study, microstrip antenna structures that are frequently used due to many advantages in biomedical applications are studied. Electromagnetic field and scattering parameter data of two antennas operating in the 2.45 GHz and 5.8 GHz operating frequency in ISM (Industrial, Scientific and Medical) band region are analyzed and compared. Pathological sample transformed form of tumor and normal skin tissue is simulated and compared in Ansys' HFSS program. Both the electric field values and the S-parameter values were compared by obtaining the values of both antennas at 2.45 GHz and 5.8 GHz from simulations. When looking at the results obtained, the difference rates in the data obtained from the antenna results radiating in the 2.45 GHz region are higher as a percentage. Thus, it is possible to say that it is more advantageous to use the 2.45 GHz frequency in antenna structures used for this purpose compared to the 5.8 GHz radiation area.

“…All these reported antennas expressed good results for wearable applications but suffered due to larger size, costly substrate, fabrications process, and narrow bandwidth. In this context, antennas with a larger size, costly substrate, and narrow bandwidth are unsuitable for WBAN applications [24][25][26]. Therefore, low-cost, compact, and wideband antennas are always inevitable for WBAN applications.…”

This study presents a low-cost, compact, flexible, and wideband wearable antenna for different wireless body area network (WBAN) band applications, covering medical body area network band of 2.4 GHz, industrial, scientific, and medical band of 2.45 GHz, WiMAX band of 3.5 GHz, and wireless local area network band of 5.2 GHz. The final antenna topology is obtained by hexagonal microstrip radiator patch fabricated on commercially available low-cost photo paper substrate and defected ground plane below the feed line acting as a partial ground to achieve a conformable structure wideband operation. The overall size of the fabricated antenna is 30 � 40 mm 2 and yields a widebandwidth of 3 GHz (2.30-5.30 GHz), radiation efficiency of 84.35%, and the highest gain of 3.48 dBi at the centre frequency of 5.2 GHz, and minimum gain of 1.91 dBi at 2.45 GHz. Furthermore, our detailed numerical and experimental investigations involving specific absorption rate performance assessment and bending analysis revealed the proposed design's excellent robustness to both human body loading and structural deformation scenarios. Therefore, simulated and measured results strongly advocate that the proposed design has profound implications for flexible and body-worn devices in WBAN applications.

“…A planar broadband antenna is integrated with an artificial magnetic conductor and provides low backward radiation smaller in size, with low SAR, high front-to-back ratio, and high gain, which are suitable for wireless body area applications [11]. A compact double circular ring, wider bandwidth and smaller size antenna, is designed for UWB biomedical application [12,13]. Circularly polarized implantable antenna loaded with complementary split ring resonators (CSRR) for real-time glucose monitoring is presented and provides high gain, wide beam width, and low SAR [14].…”

Wireless body area network (WBAN) incorporates a wireless sensor network and wearable devices in miniature size. In this paper, a dual-band microstrip patch (DBMSP) antenna as a sensor with a modified split ring resonator (SRR) and defective ground structure (DGS) is proposed for muscle mass measurement and prediction. Modified SRR on the ground plane forms a defected ground structure (DGS) for back radiation reduction and suits muscle mass measurement. The proposed dual-band microstrip patch antenna resonates at 5.2 GHz and 8.4 GHz, with impedance bandwidth of about 0.9 GHz and 1.89 GHz, input reflection coefficient is about -21.12 dB and -14.5 dB, respectively. This DBMSP antenna has an efficiency of 99.9%, with a negligible amount of specific absorption rate (SAR). From the proposed DBMSP antenna sensor, muscle mass is predicted from human muscle. The proposed antenna is fixed on the ventral surface of the forearm and biceps. DBMSP antenna sensor detects electromagnetic energy from muscle tissues under radiating near-field conditions. The muscle tissue signal is acquired through the proposed DBMSP antenna. The acquired antenna process with nondecimated wavelet transform (NDWT) and discrete wavelet transform (DWT) algorithms for noise reduction. Further, early prediction of muscle mass prevents humans from lack of protein and oxygen levels in the blood and avoids major issues in human health. The proposed DBMSP antenna-based muscle mass measurement achieves 89% accuracy when compared with laboratory measurement.
