This paper deals with the parametric study of novel monopole antenna with circular ring shape in body-implantable applications. The miniaturized antenna is placed inside skin phantom tissue of human body that has a dimension of 5x5x0.125mm3 . A single wide band is observed for this implantable antenna design with better return loss. The suggested antenna uses a mid-band frequency range of 1520–1693 MHz, ISM band ranging from 433.1–434.8 MHz, and Medical Implanted Communication Service of 402–405MHz. The antenna exhibited compact size and fabricated on RT Duriod 5880 substrate with the property of flexible/ bendable in nature. A significant compact design of the antenna is achieved by using similar dimension of rectangular arms on the circular shape ring patch.The compact dimensions, reduced ground plane, and bandwidths of the suggested antenna are its salient characteristics with the obtained bandwidths are of 500MHz, 550MHz, 650MHz, 585MHz, 690MHz, 652MHz and 740MHz and acceptable gain levels in comparison with other implanted antennas working in the ISM band. The simulated realized gain values are -13.3dBi, -22.1dBi and -18.4dBi respectively.

Abstract


This paper deals with the parametric study of novel monopole antenna with circular ring shape in body-implantable applications. The miniaturized antenna is placed inside skin phantom tissue of human body that has a dimension of 5x5x0.125mm3 . A single wide band is observed for this implantable antenna design with better return loss. The suggested antenna uses a mid-band frequency range of 1520–1693 MHz, ISM band ranging from 433.1–434.8 MHz, and Medical Implanted Communication Service of 402–405MHz. The antenna exhibited compact size and fabricated on RT Duriod 5880 substrate with the property of flexible/ bendable in nature. A significant compact design of the antenna is achieved by using similar dimension of rectangular arms on the circular shape ring patch.The compact dimensions, reduced ground plane, and bandwidths of the suggested antenna are its salient characteristics with the obtained bandwidths are of 500MHz, 550MHz, 650MHz, 585MHz, 690MHz, 652MHz and 740MHz and acceptable gain levels in comparison with other implanted antennas working in the ISM band. The simulated realized gain values are -13.3dBi, -22.1dBi and -18.4dBi respectively.
