Case Study

Implantable Planar Antenna Simulation

The wide and fast growing application of wireless devices yields to a lot of concerns about their safety standards related to electromagnetic radiation effects on human body. Interaction between human body tissues and Radio Frequency (RF) fields are important. Many researches have been done to investigate the effects of electromagnetic radiation on human body. The Specific Absorption Rate (SAR), which measures the electromagnetic power density absorbed by the human body tissue, is considered as an index by standards to regulate the amount of exposure of the human body to electromagnetic radiation.

  • In this case study, the design modification and tuning of antenna performance were studied with the implantable antenna placed inside the skin tissue of ANSYS human body model.
  • The resonance, radiation, and Specific Absorption Rate (SAR) of implantable PIFA were evaluated with ANSYS HFSS (High-Frequency Structural Simulator) which is based on Finite Element Method (FEM).
  • All simulations have been performed on the ANSYS Cloud platform from UberCloud with a 40-core Nephoscale cloud server with 256 GB RAM. These simulations were about 4 times faster than on the local 16-core desktop workstation.
