Abstract
A holder for a mobile communication device comprises a receptacle for optimally reducing the SAR value of a mobile communication device secured within the receptacle. At least one material portion, a patch, causing electromagnetic losses may be placed within the receptacle to optimally reduce exposure to low level radio frequency energy to an individual carrying a mobile telephone secured within the receptacle. The patch formed of electromagnetic field reducing material may be placed in one or more particular areas of the receptacle to attenuate one or more corresponding regions of the mobile telephone in which the SAR value is substantially at a local maximum. This may allow a reduction of the SAR value of a mobile telephone while limiting the performance loss associated with the reduction of the SAR value of the mobile telephone when the mobile telephone is secured within the receptacle.
