| Abstract | Recent wireless technologies in particular the RFID technology has been stimulating significant interest in several applications including in healthcare industries owing to their benefits to human being. The RFID offers a better identification system compared to a barcode scanning system due to its simple contact method to the receiver, its storage media, and good accuracy and reliability. In addition, body-centric wireless communications systems (BWCS) have received a great attention recently since their numerous applications including in combination with low rate wireless personal area (LR-WPAN)/Zigbee technology for medical data monitoring system. This paper presents a design of planar loop antenna for wearable health monitoring device aiming at BWCS applications. According to the calculated link budget, the antenna is set to operate at the center frequency 924 MHz, with the gain more than -35 dBi and wide beamwidth pattern in horizontal-plane. The antenna is put in the vicinity of the human body by about 2-mm from the human body surface. The antenna is numerically analyzed in the proximity to a three-layer phantom model, a voxel human body model and homogeneous muscle-equivalent model. As the result of simulation, the antenna performance shows 1.005 of VSWR, minimum gain by -22.18 dBi on axial-plane and -24.74 dBi on sagittal-plane (0≤El≤180°) at 924 MHz. The measurement is conducted to validate the simulation results by using a muscle-equivalent semi-solid phantom. The measured results tend to show good agreement with the simulation especially in terms of reflection coefficient and radiation pattern. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
