Abstract: The proposed design of a Microstrip patch antenna for biomedical applications is represented in this paper which is operating at 2.4GHz frequency range in ISM Band. The significant feature of the proposed antenna is to make it perfect for on-body biomedical applications. The Polyimide substrate which has dielectric constant (εr) of 3.5, thickness of 0.0508 mm and loss tangent 0.0027 is used. The proposed antenna dimension is 21 mm x 17 mm x 0.0508 mm length, width and height respectively. The radiating patch has the length and width is 20 mm and 16.5 mm respectively. The antenna is designed using 3D EM simulation tool and S11 response is of less than -10dB. The designed and developed antenna has been fabricated in the laboratory and measured using RF equipment for parameters like reflection coefficient, VSWR and input impedance. The experimental results agree well with simulation results which proves that it is a good candidate for Biomedical applications.
