This study exhibits a circularly polarized (CP) conformal antenna actualized by using a jute textile as a substrate. Its sensing 3.5, 4.9, and 5.8 GHz in the Wi-MAX, WLAN, and ISM radio bands. The topology of the proposed antenna has relied on a curvature structure as the prime radiating element, and ground structure whirled in contradictive arrangement to the patch. Conductivity was materialized by applying copper paint through the traditional painting approach, i.e., brush painting. This fabrication method allows attaining the conformability with minimized size, lightweight, and low sensitivity to the environment without weakening the radiating performance. These attributes allowed the jute textile antenna appropriately for the incorporation in wearable devices for body-driven applications. The electromagnetic properties of the projected jute textile antenna accomplished in simulations were confirmed through the measurement of the antenna in an anechoic chamber. The CP jute textile antenna shows a peak gain of 4.93, 8.86, and 10.07dBi at 3.5, 4.9, and 5.8 GHz (WiMAX, WLAN, and ISM).
