An AMC Based Antenna for Telemedicine ApplicationsAbstract
In this paper, we present an antenna design for telemedicine applications operating in the Industrial Scientific Medical (ISM) 2.4 GHz band. The design is based on a printed monopole antenna integrated with an artificial magnetic conductor (AMC) ground plane. The AMC ground plane is utilized to isolate the user’s body from undesired electromagnetic radiation in addition to eliminating the antenna’s impedance mismatch caused by the proximity to human tissues. Moreover, specific absorption rate (SAR) is analyzed based on a numerical human body model (HUGO) to assess the design feasibility. Results show that the radiation characteristics, impedance matching, and SAR values of the proposed design are significantly improved compared with conventional antennas.
