Wireless body area network (WBAN) applications have broad utility in monitoring patient health and transmitting the data wirelessly. WBAN can greatly benefit from wearable antennas. Wearable antennas provide comfort and continuity of the monitoring of the patient. Therefore, they must be comfortable, flexible, and operate without excessive degradation near the body. Most wearable antennas use a truncated ground, which increases specific absorption rate (SAR) undesirably. A full ground ultra-wideband (UWB) antenna is proposed and utilized here to attain a broad bandwidth while keeping SAR in the acceptable range based on both 1 g and 10 g standards. It is designed on a denim substrate with a dielectric constant of 1.4 and thickness of 0.7 mm alongside the ShieldIt conductive textile. The antenna is fed using a ground coplanar waveguide (GCPW) through a substrate-integrated waveguide (SIW) transition. This transition creates a perfect match while reducing SAR. In addition, the proposed antenna has a bandwidth (BW) of 7–28 GHz, maximum directive gain of 10.5 dBi and maximum radiation efficiency of 96%, with small dimensions of 60 × 50 × 0.7 mm3. The good antenna’s performance while it is placed on the breast shows that it is a good candidate for both breast cancer imaging and WBAN.

This work presents the design and optimization of an antenna with defected ground structure (DGS) using characteristic mode analysis (CMA) to enhance bandwidth. This DGS is integrated with a rectangular patch with circular meandered rings (RPCMR) in a wearable format fully using textiles for wireless body area network (WBAN) application. For this integration process, both CMA and the method of moments (MoM) were applied using the same electromagnetic simulation software. This work characterizes and estimates the final shape and dimensions of the DGS using the CMA method, aimed at enhancing antenna bandwidth. The optimization of the dimensions and shape of the DGS is simplified, as the influence of the substrates and excitation is first excluded. This optimizes the required time and resources in the design process, in contrast to the conventional optimization approaches made using full wave “trial and error” simulations on a complete antenna structure. To validate the performance of the antenna on the body, the specific absorption rate is studied. Simulated and measured results indicate that the proposed antenna meets the requirements of wideband on-body operation.

“…Medical imaging methods such as x-ray, computed tomography, magnetic resonance imaging, and PET are widely used today to determine whether a person has cancerous cells in their body [3,4]. Although X-ray is a cheap and simple imaging technique, it can cause harm to the body due to its ionizing feature.…”

Telemedicine and mobile healthcare communication devices require compact antennas with superior performance and reduced size and weight. The design and development of such antennas for broadband applications are challenging for many researchers. In this study, a wearable rectangular microstrip antenna was designed and implemented to detect many tumors. The patch and ground part of the antenna, which can be used as both a transmitter and a receiver in microwave imaging systems, are made of copper tape, graphene, conductive paint, and the substrate is made of felt (Ɛr = 1.3). Antenna parameters were optimized using the CST Microwave Studio program. The conventional microstrip antennas have a narrow band and low gain. The antenna in this study is designed and implemented differently from the conventional microstrip antennas and can be easily used in applications requiring ultra-wideband. In addition, the radiation characteristic of the designed antenna is quite good, and the electric field change around it is at a level that will not cause any health problems. The variation of the conductivity values of the organs in the human body is high in the 1 GHz-10 GHz frequency band. The antenna, which is designed based on the fact that the conductivity values of healthy tissues and tumor/cancer tissues are different, can be used in microwave imaging systems to detect tumors in organs such as the lung, brain, liver, and kidney. Also, the designed antenna is in a wearable form, allowing continuous monitoring of patients with high cancer risk. In this article, a microstrip patch antenna with a flexible substrate with copper tape, conductive paint, and graphene-based conductor that can be used for imaging and telemedicine applications is proposed, and its performance is experimentally analyzed. A standard and low-cost 3D printer are used to produce the graphene-based conductive part. In addition, copper tape and conductive paint materials were used to produce the patch part with an easier and cheaper method without a special device. The performance, return loss, and gain of the produced antennas were analyzed both in simulation and experimentally.
