In the advancement of bio medical devices amidst the situation of pandemic ,people suffer from breathing issues and several devices are taken on account to measure the breathing patterns of the individuals ,the field of interest in RF and microwave applications inspired to design a wearable antenna used on - body wireless communication systems to operate on 2.45 GHz WLAN band .A microstrip patch antenna design is proposed based on the substrate there is performance improvisations , the substrates differ by material and thickness taken polyester with permittivity of 1.9 .The antenna is supposedly designed to have a value of VSWR<2 and a healthy gain for measuring the signal strength and evaluate into breathing frequencies categorised for males and females When it is wearable ,there is different type of design methodologies involved namely silver plated fabric , Inverter F antenna , 3D printed patch antenna etc. ,the reason for choosing microstrip patch antenna is that it has ground plane to avoid frequency radiation entering into the human body and with advancement in miniaturisation of devices microstrip patch antenna is best on sight The proposed antenna is designed on CST (Computer Simulation Technology) and results are provided .
