A Novel approach forWearable Antenna Design for Biomedical Applications

A low profile wearable antenna for the different applications of Body Area Networks is presented. Wearable microstrip patch antenna for development in different applications in the area of WBAN. Many breakthroughs of wearable devices, together including their flexibility, suggest a real time monitoring with WBAN technology of the human vital signs such as pulse rates, blood pressure, and body temperature. The proposed antenna works in the operating frequency of 2.45 GHz which falls under the industrial, scientific and medical (ISM) frequency band. The designed antenna uses the flexible Polyimide substrate with a relative permittivity of 3.5 and thickness of 0.1 mm. The antenna is tested on a three layered human phantom model. The antenna parameters of return loss, VSWR, Specific Absorption Rate (SAR), gain and low value are established, while Return lost at 2.45 GHz is approximately − 23.22 dB with a VSWR value of 2.45 GHz being 1.13, which determines improved matching impedance. The 2D and 3D gain, and radiation patterns have been determined. The designed antenna is simulated with a three layered phantom model using a High Frequency Structure Simulator (HFSS).The simulated model is tested using Network Analyzer and Anechoic chamber and fabricated.
