Wireless body area networks have paying moreattention in the recent decade. The microstrip textile antenna usedfor wireless applications (ISM Band) such as emergency rescue,health monitoring and medical care. In this paper, the squarepatch microstrip textile antenna is introduced which is mountedon the flexible jeans substrate. The physical size of thesuggested/simulated textile antenna is 52.99 X 45.23 mm2 & thejean’s material is used as substrate with its relative permittivity ofɛr = 1.67. The proposed antenna is radiating at the centerfrequency of 2.45 GHz with a return loss of -15.76 dB & VSWR1.389, the far field directivity of an antenna is 8.05 dBi at2.45GHz. The designed antenna is wearable on the clothesbecause the use of textile material for antenna fabrication bykeeping SAR at 1.6 W/Kg as shown in figure 1. This designed microstrip textile antenna used to make potable WiFi in wireless communication.

The Microstrip Textile antenna is the best alternative to theconventional antenna to avoid the change in antennaperformance characteristics due to bending & crumplingconditions.In this paper the rectangular microstrip textile antenna isdesigned in the ISM band with an operating at the centerfrequency of 2.45 GHz & the designed antenna providesreturn loss of -15.76 dB &has a directivity of 8.05 dBi used for wireless application. The radiated efficiency of antenna is88.61% which is efficient for WiFi application. In future multiband microstrip, textile can be designed withlightweight by reducing substrate height. The antenna will bemade compact by increasing ɛr value to the desired level.

In the recent era of communication, the wireless body area network (WBAN) plays a vital role in WiFi application. The proposed antenna is designed in the ISM band and used for wireless application at an operating frequency of 2.45GHz. Normally WiFi operates in the frequency range of 2.4GHz to 2.485GHz in India. Because of the use of the textile substrate as jeans, the antenna is mounted on the clothes & used for WiFi communication. The microstrip antenna is mostly used in wireless application due its properties compact size, lightweight & simple to fabricate. The basic structures of printed microstrip antenna consist of top patch & ground plane which is made up of thin copper layer of 30-35 micron. These two copper layers are separated by dielectric substrates.
