Antenna modeling in smart phone devices, using electromagnetic simulation software, has improved significantly by allowing the simulation of the antenna behavior in complex environments surrounding the antenna. Thus, current electromagnetic software allows the simulation of handheld antennas regarding not only the human presence (such as human head and hand) but also the presence of nearby components (such as cameras, batteries, displays, and speakers).
The phantom head model, called SAM (Specific Anthropomorphic Mannequin), was first introduced in 2002. The material inside the plastic shell has specific electrical properties, that is, dielectric constant and conductivity that are modeled closely to the real human head. Modeling the hand was more difficult and it took longer to get to the final set of phantom hands.
