Flexible Graphene Waffle-Typed Antenna for Skin-Typed Medical Applications
The objective of this paper is to present a study of the graphene waffle-typed antenna, worked for skin-typed medical applications such as microwave breast imaging. The antenna is designed to operate at 402-405 MHz medical implant communication service band (MICS). The antenna is required to be flexible or bendable enough for a curve-fit into the patient skin, especially at the chest location. The DuPont Kapton with the thickness of 0.25 mm is used as the substrate. The graphene conductor is used due to its flexibility. The antenna is designed by using XFDTD program with two different superstrate materials, the Kapton and household silicon. The genetic algorithm is applied for tuning the antenna parameters. The curved model is tested on the chest with different facets curved. The return losses are compared, and the I-g average specific absorption rate, SAR, are defined for the maximum input power available. The antenna with 32 curved facets and 22.5 degree bending model were compared to the conventional style. The maximum input powers for the antenna with Kapton and silicon superstrates are 4.43 mW and 4.46 mW, respectively.
