A 2.4 GHz antenna for medical implanted communications

There is a huge interest of tissue implanted devices for wireless medical applications with wider bandwidth as medicine day by day and more and more is associated with electronics and electromagnetics. The current Medical Implant Communications Service (MICS) with frequency range of 402–405 MHz is not suitable to transfer image data due to bandwidth and regulation limitation. A key component of wireless implanted device is an antenna, and there are several issues to consider while designing an in-body antenna, including power consumption, size, frequency, biocompatibility and the unique RF transmission challenges posed by the human body. This paper mainly deals with an implantable antenna design for the frequency band of 2.4 GHz.
