In proposed design the wearable circular microstrip antenna of radius of patch is 14 mm and the top of patch consist of two square slits of dimensions 5x5 mm2 and 10x10mm2 and the ground structure is made partial of 28mm x 86mm. Due to the properties of jeans fabric as low cost, flexible the antenna is made wearable. In the proposed study, circular microstrip textile based antenna has been designed for the ISM band of resonating frequency of 2.4GHz. The proposed structure provided the triple band as the radiating frequencies of 2.4GHz for WiFi, 6.4GHz for WiMAX and 12GHz for 5G communication applications. The simulated and fabricated results such as return loss, VSWR and gain - directivity etc. are analyzed and compared for the frequencies of 2.38GHz, 6.4GHz and 12GHz. In this proposed antenna, the bandwidths of antenna are obtained of the order 700MHz, 3.43GHz & 2.75GHz and gain of antenna are of the order 1.89 dBi, 3.98 dBi & 4.86 dBi.
