摘要

Low specific absorption rate (SAR) compact hexaband planar inverted-F antenna (PIFA) with independent resonant frequency control has been studied in this letter. Two trapezoidal-shaped slots are etched on the coplanar waveguide-fed PIFA-radiating plate to create two independent resonant frequencies as well as the fundamental PIFA itself. Three coupled slots are added within the ground plane to create an additional three independent resonant frequencies with slight effect on the other resonant frequencies. Multiband capabilities with bandwidth enhancement and acceptable SAR values are realized for different wireless communication applications. The SAR in the presence of human head is investigated by using CST 2012 Microwave Studio Hugo Voxil Model. The proposed antennas are fabricated, and there is a good agreement between measured and simulated results.
