In present years, the academic and scientific societies have giving more attention to flexible technology. When antenna performance is very poor due to its surrounding environment, flexible antennas have become important. A flexible patch antenna is presented using a Jute fiber with improved performance. It designed with jute substrate material and copper conducting layer for ground and patch. Rectangular stripped structure has been used in the antenna for enhancing the parameter and optimizations. The antenna is designed at the resonating frequency of 2.45 GHz. The efficiency of antenna is measured from return loss, directivity and gain. It can be used for military application, ground radar position, search and rescue application. It is capable for the biomedical application due to its minimized SAR value. It is used due to its inexpensive cost and abundant available of jute substrate.
