Patent abstract
A low Specific Absorption Rate (SAR) gamma-folded loop-shaped antenna has a resonant structure including two arms connected to an elongated loop and has dual resonant elements in the 5 GHz WiFi band, dividing emissions in the 5 GHz bands between two emission hotspots. The elongated loop folds back upon itself 180 degrees. The antenna also may include a discontinuous transition in cross-sectional area tuned to boost emissions in the 2.4 GHz WiFi band. The antenna is designed for compact handheld devices that may be held close to a person's body, reducing the intensity of energy irradiated into the body in the 5 GHz band by distributing the energy across spatially-separated dual resonant elements.
