Super wide band antenna

Developing antennas into textile material is a potential way for facilitating many wireless applications, such as health monitoring of patients, fire-fighting, rescue work, and space and military personal communications. The increasing interest in wearable product such as medical devices, health monitoring, sport wear and military domains promises to replace wired- communication networks in the near future in which antennas play a paramount character. They can play a vital role in monitoring heart, blood rate or sending emergency signal for heart rhythm disorder and health irregularities. Moreover, wireless communication system can be used to determine a soldier’s physiological status including heartbeat, blood pressure, respiration and body temperature. Body area networks have special features and advantages that make them different in comparison to other wireless systems.  The devices deployed within BAN have limited sources of energy due to their compact and small size. Inspired by the idea of user centric propose to future communication technology, many research topics have been initiated, under the concept of wearable devices, to integrate antennas into the clothes with regards to size reduction and cost effectiveness. This paper presents the possible investigation for the super wide band (SWB) MIMO antenna made from 100% textile material. In this paper, SWB MIMO antenna presented for wireless communication with three different substrate materials are presented and implemented with textile material. This antenna resonates at frequencies from 1.5GHz to 38.18GHz. In addition, the antenna provides with compact, low mass, flexible, washable and robust material. Here, the performance of this antenna in terms of return loss and radiation pattern deformation at different frequencies is observed as well. Lastly, the antenna is verified by simulated and measured result. Wireless body area networks (WBAN) are a natural progression from the personal area network (PAN). Having such novel uses in pervasive system for soldier, BAN is regarded as a promising interdisciplinary technology that could have a huge impact on advancing Health-IT and telemedicine with its widespread commercialization. In addition, the wearable nodes can also communicate to a controller device that is located in the vicinity of the human body. The effect of the human body on the operation of antennas located in close proximity has been investigated widely and thoroughly in open literature including the absorption of energy within the body and on specific absorption rate (SAR) for proximate antennas and of the propagation on and off the body.
