A symmetric multilayered embroidered textile antenna is proposed in this article. The proposed antenna is designed at industrial, scientific, and medical band frequency of 2.45 GHz, to be used as a wearable made of Zari and cotton cloth. An end‐to‐end slot has been introduced to improve return loss and efficiency. The four‐layered antenna is fabricated using conventional embroidery and the layers are sewn together to form the entire structure. Measurements on the fabricated antenna are performed to validate the characteristics of the structure in bent, crumpled, and wet conditions. Results with regard to return loss, gain, bandwidth, and radiation pattern were presented to prove the usefulness of the structure. Furthermore, the antenna was integrated with Arduino Uno development board and tested for data transmission as a wearable system.
This paper proposes a unique, first of its kind fabrication technique for the making of textile antennas. A novel method that provides scope for automation in textile antenna production is presented here. A completely integrated textile antenna fabrication method that eliminates the tasks of positioning and fastening of the various components of a patch antenna is discussed. The technique employs multilayer weaving for the production of a wearable antenna on a cotton substrate. Silver yarn is used for the conductive regions of the textile antenna. Two layers of woven cotton serve to isolate the radiating patch from the ground plane of the antenna. The designed antenna was chosen to operate at the frequency of 2.45 GHz for Wireless Local Area Network. The built prototype resonated at 2.43 GHz with a |S11|of −18.62 dB. The integrated textile antenna exhibited a gain of 1.06 dBi at 2.43 GHz.
