Design and fabrication of rectangular microstrip patch antenna at ISM band for medical applications

In this world the design of antenna for ISM band for medical purpose were developed fastly in the field of wireless communication. This paper focuses the design and implementation of rectangular microstrip patch antenna (RMP) for ISM band. This antenna covers three region, substrate made-up of FR4 material, patch and ground made up of copper material. This antenna provides good return loss as -17.61dB, VSWR as 1.303, Impedance as 42.6-ohm, gain(dBi) as3.90694, directivity(dBi) as 4.34724, efficiency as 90.359 %, bandwidth as 0.15GHz and Fractional Bandwidth as 0.066 GHz. This type of antenna is more suitable for biomedical application to monitor the patient health condition and transferring the bio information to remote area.
