In this paper the design of a wearable antenna for industrial, scientific, and medical (ISM band) applications at 2.4 - 2.45 GHz and 5.7 - 5.85 GHz is discussed. The rectangular microstrio patch antenna is considered and two series of slots are implemented with same length and different length. The conductive and ground planes are made from copper and cloth, respectively. Copper serves as a conductor in this case, while textile material serves as a barrier between the human body and the antenna. Micro strip feeding is supplied here to improve the antenna's reliability. The performance of the antenna will be evaluated using the simulation and practical as well, the reflection coefficient, VSWR, gain and radiation pattern of Microstrip textile antennas is obtained which used in a variety of ISM band applications.
