| Abstract | The design of a folded open-ended slot antenna for an early-stage congestive heart failure (CHF) detection system operating at ultra-high frequency (UHF) is presented. The antenna is formed using a three-dimensional open-ended slot with a compact size of 0.24 λ0 × 0.09λ0 × 0.04 λ0 (λ0 is the lowest operating frequency of the antenna), and a slotted microstrip feeder used to achieve wide operating bandwidth of 58% (550-1000 MHz). A CHF detection system is then built using the proposed antenna, a compact microwave sensor, and a differential detection technique. The main objective of such a system is to map the torso area searching for any fluid accumulation in the lungs as the main symptom of CHF. To that end, a pair of the proposed antenna is attached to an adjustable platform to vertically scan the torso. A differential detection technique is applied on the backscattered signals to map the scattering profile of the torso and detect any changes in the electrical properties of the lungs caused by fluid accumulation. A detection threshold is applied to differentiate between healthy and unhealthy cases. The obtained images have a pixel resolution of 0.1 cm in depth and 1 cm in height. The experimental results on an artificial torso indicate that the system can detect fluid differences as small as 4 mL, with a measurement error of less than 3%. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
