Abstract

In this paper, a stripline-fed slot antenna for implanted devices is proposed. The antenna is characterized for the Industrial, Scientific and Medical Radio (ISM) band and applied to be implanted in muscle layer of the human body. Double-layered structure with slot both on top and bottom side of the antenna is used. The stripline-feed prevents the loss along the feed line regarding the in-body application and allows very high radiation efficiency. A miniaturization technology is applied by using a meandered line for the radiator connected with the stripline. The simulation and measured results show that the antenna with a small size of 12.5×14.7 mm² features very good impedance matching in operational frequency band and a relative bandwidth of 16.9%, which indicates a high potential of this antenna for biomedical applications.
