In this paper, a flexible reconfigurable antenna suitable for wearable applications is presented. Thanks to the reconfiguration mechanism, the antenna is robust in terms of impedance matching to the folding of the structure.
In this paper, the effect of the human body proximity on LPWAN antennas is investigated. Both numerical and experimental tests are performed on two different IoT devices. The obtained results show that the performance degradation caused by the body …
In this paper, a fast characterization technique for on-body small devices is presented. This method is used to extract the radiation performance of two different structures placed on a belt over a human abdomen at 868 MHz. Results show that the …
The article describes a low-cost and open IoT platform for rural applications in developing countries. Using the latest low-power, long-range radio technologies and off-the-shelves components, the platform can be quickly deployed and customized for a …
This letter proposes an approach for the realization of three-dimensional flexible antennas based on the use of liquid metal and additive printing technologies. As a representative example, a miniaturized inverted-F antenna (IFA) operating at 885 MHz …
Body Area Networks (BAN) have received significant attention in recent years and have found a wide range of applications, including wearable devices for fitness and health tracking, and mobile communications. Battery lifetime continues to be the main …
The feasibility of using ultra-narrow band (UNB) antennas for internet-of-things applications is discussed. An analysis aimed at evaluating the antenna miniaturisation limits when there are almost no bandwidth requirements is performed. Both …
