Semicircular shape hybrid reconfigurable antenna on Jute textile for ISM , Wi‐Fi , Wi‐MAX , and W‐LAN applications

Abstract

This article presents the development of a conformal reconfigurable frequency circularly polarized jute textile antenna, working at 2.4, 3.5, 5.8, and 5.9 GHz in Wi-Fi, Wi-MAX, Industrial, Scientific and Medical radio bands and W-LAN. The antenna topology is based on a semicircular structure as the main radiating component. The conductivity is realized by using copper paint, which was brush-painted. The patch structure is rehashed in another side of the substrate against the ground with a rotation turn 180. Two BAR64-03 W PIN diodes switches are placed in between a semi-elliptical structure and a rectangular structure on the bottom side of the ground plane. By governing the state of the switches, this antenna can operate at different operating frequencies. Furthermore, the antenna has an accomplished axial ratio (AR) of less than 3 dB for resonating frequencies at all four switching states. Other electromagnetic properties of the proposed jute textile antenna accomplished in simulations were confirmed through the measurement of the antenna in an anechoic chamber. The reconfigurable circularly-polarized jute textile antenna shows a peak gain of 4.93, 5.67, 8.86, and10.07 dBi at 2.4, 3.5, 5.8, and 5.9 GHz (Wi-Fi, Wi-MAX, ISM, W-LAN).

On Body and Off‐Body Performance Analysis of an Ashoka Tree Shaped Wearable Textile Antenna for Biomedical and Military Applications

“…In the above section, jean textile is selected as a proper textile substrate due to its strong and high flexible fiber behavior. To realize the conductivity of the radiating elements, various techniques were proposed, like the use of conductive paint (Sandeep et al., 2020), adhesive copper tape (Ram Sandeep et al., 2020), embroidering and stitching of the conductive threads on the substrate (Prabakaran & Madhav Boddapati, 2020), and the use of conductive fabrics (Hertleer et al., 2009). Among the methods mentioned above, the conductive fibers approach is easy to implement and of low cost; the main advantage of the fabrication method is that the conductive textile is highly conductive in nature because it's formed by the amalgamation of the textile fibers with metal threads.…”
