Abstract

An implantable wireless data transmission system, under development, requires the implanted antenna to be located under the skin of a rat. Here we investigate variations in the resonance frequency of a commercial antenna (ANT403 SP1, Antenna Factor ™) with and without covering by rat skin. Frequency shifting due to ageing effects of the rat skin is also measured in this experiment. It is found that 15%-20% decrease in the resonance frequency may occur when the antenna is covered by rat skin, which has an average thickness at around 2mm. However, only slight frequency variations were observed due to the ageing effect of rat skin. Fresh rat skin samples were collected and stored in salt solution before, and after, measurements. A comparative study of frequency shifting between micro-strip (MS) feed and co-planar waveguide (CPW) feed of the antenna is highlighted in this paper.
