Abstract

This paper presents a rectangular dual-band gap loop antenna designed for 900/1800 MHz mobile handsets with proximate head and hand model. The dual-band antenna consists of two straight wires, each with a single right-angle bend, one end directly excited, the other mounted on the ground plane. The ends of the wires are separated by a small gap. Real-time experiments are performed on a prototype embodiment in free space and also when held close to a real human head. SAR effects are analyzed numerically using two separate MRI-based tissue-classified head models, a modified-Brooks model and an NIT head model. Included a hand model is used to simulate a hand holding the handset. The characteristics of the two models are discussed. Differences for the absorption power and SAR distribution between the two models are discussed in terms of importance for evaluation of cellphone health hazards.
