SAR Reduction in Slotted PIFA for Mobile Handsets using RF Shield
نویسندگان
چکیده
This paper proposes a multiband handset antenna combining PIFA and novel slots on radiating patch of PIFA for mobile applications. Two slots were introduced in order to embody 900 and 1800 MHz band. Radiation patterns are computed in free space as well as in the presence of head. Specific Absorption Rate (SAR) of slotted PIFA antenna is calculated and is compared with the SAR limits in the safety standards. SAR is investigated, by discussing the effect of RF shield which is introduced between slotted PIFA antenna and head. Simulation results show that with the introduction of RF shield of thickness of 1mm, SAR reduces by 12%. .All simulations are done in FEKO software.

A novel monopole internal antenna for mobile handsets is presented. The antenna, called the MB antenna, is a modified monopole whose radiating element is implemented in parallel proximity of a ground plane hence allowing for use as an internal antenna in handset applications. Simulation studies indicate that the proposed MB antenna has superior performance over PIFA antennas commonly used in mo...

This paper presents the numerical evaluation of the microwave absorption at 2.4 GHz (ISM band) in a homogeneous rectangular head model. Specific absorption rate(SAR) reduction in the head model is achieved by attaching nickel-zinc spinel ferrite sheet resonating at 2.4 GHz to a mobile phone. RF shields made of ferrite sheets are used to suppress surface currents on the mobile phone. Simulations...

A capacitively loaded planar inverted{F antenna (PIFA) is proposed and studied. It is found that the capacitive load reduces the resonance length of the PIFA from =4 to less than =8. A design with a bandwidth of 178MHz centered at 1.8GHz is provided to demonstrate that compact antennas for mobile telephone handsets can be constructed using this approach. The nite diierence time domain method is...
