In this paper, wearable textile antenna is presented for detecting breast cancer in early stages. The proposed antenna is designed and optimized using a 0.5 flexible cotton material substrate to operate at UWB with a wider frequency range of 3 GHz - 10.5 GHz. In this paper, the performance of the antenna is investigated in terms of reflection coefficients, gain and radiation patterns by bending the structure in several different degrees. A line slot is used at the ground level to enhance the antenna resonate performance overdesigned spectrum. Moreover, the antenna has good gain and efficiency over the bandwidth of 3.47 dBi and 92.3 % respectively.
