Abstract: In this review paper, research progress on implantable antennas for wireless biomedical devices is discussed and summarized. An implantable antenna is a key component for radio frequency linked telemetry as many challenges arise. An implantable antenna needs to meet requirements such as compact size, operating bandwidth, sufficient radiation efficiency, and patient safety. The purpose of this paper is to give an overview of the current progress and achievements and address the challenges for implantable antenna design. Firstly, the overview of the requirements related to the implantable antenna design is provided. Then simulation and test methods for implantable antenna design are examined. Different antenna types, operating frequency bands and design environments are reviewed. Finally recent research topics on implantable antennas are introduced.

Index Terms: Implantable antenna, miniaturized antenna, small antenna, biomedical application, biomedical telemetry, capsule antenna, wireless data telemetry, far-field wireless power transfer.
