This letter presents the proof-of-concept of the fabrication and performance analysis of a flexible and stretchable wearable antenna on a three-dimensional (3-D) printed substrate. It presents the details of the 3-D printing of the substrate, brush-painting of the antenna, as well as the simulation and measurement results of the antenna. In addition, the bending test is done to check the limitation...
This paper presents a circularly polarized antenna on thin and flexible Denim substrate for Industrial, Scientific and Medical (ISM) band and Wireless Body Area Network (WBAN) applications at 2.45 GHz. Copper tape is used as the conductive material on 1 mm thick Denim substrate. Circular polarization is achieved by introducing rectangular slot along diagonal axes at the center of the circular patch...
Embroidered RFID tags can be used in fabric integrated on-body applications such as tracking and access control. Moreover, embroidered antennas are important also in other wearable, body-centric wireless systems. The durability of the embroidered tag antenna is essential for garment-integrated applications due to the high probability to encounter different environmental conditions. In this paper,...
This paper presents a wearable RFID tag antenna for the European UHF RFID band. The antenna is a one-layer dipole structure optimised to operate very near the human body. At the centre frequency (866 MHz), the tag is readable from a 5-to-6-metre distance if it is worn at 1 cm or more from the body. With the antenna worn on the body, the radiation pattern covers one hemisphere. The changes in the frequency...
