In this paper, a design of a miniature antenna for biomedical implant applications is presented. The proposed structure consists of a printed antenna designed to cover all frequency bands below 1 GHz and is dedicated to biomedical applications with good matching, omnidirectional radiation, and a maximum realized gain of ？26.7 dBi. It offers two bandwidths of 270 MHz and 762 MHz respectively. A Phantom model of the elliptical cylinder of 180 × 100 × 50 mm3 was used to simulate the electromagnetic radiation inside the human body. The tissue considered is equivalent to a muscle with a relative permittivity of 57 and a conductivity equal to 0.79 S/m. We also studied the antenna behavior when close to the internal electronic components. The simulation showed that the antenna remains robust in such an environment. Finally, the Specific Absorption Rate of the muscle was evaluated when the antenna was fed with 1 V. The evaluation proved that the calculated value of 0.48 W/Kg is well below the limit value imposed by the International Commission on Non-Ionizing Radiation Protection.
