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.

What is claimed is: 1. A holder for a mobile communication device generating a region of substantially maximum elevated electromagnetic radiation, comprising: a receptacle for receiving and holding the mobile communication device, said receptacle including a first wall, second wall and third wall,

What is claimed is: 1. A holder for a mobile communication device generating a region of substantially maximum elevated electromagnetic radiation, comprising: a receptacle for receiving and holding the mobile communication device, said receptacle including a first wall, second wall and third wall, the receptacle comprising a pouch for removably receiving the mobile communication device, the pouch substantially enclosing the mobile communication device when the mobile communication device is received in the receptacle; and a patch held in proximity to the region of substantially maximum elevated electromagnetic radiation by the receptacle while the mobile communication device is received in the receptacle for attenuating electromagnetic radiation emitted from the region, said patch being placed only in a portion of said first wall of said receptacle, wherein the patch attenuates electromagnetic radiation from the mobile communication device so that the specific absorption rate (SAR) of the mobile communication device is reduced when the mobile communication device is received in the receptacle. 2. The holder as claimed in claim 1, wherein the receptacle is wearable by a user of the mobile communication device so that the mobile communication device is held adjacent to the body of the user for providing body worn use of the mobile communication device. 3. The holder as claimed in claim 2, wherein the receptacle holds the patch between the body of the user and the region of substantially maximum elevated electromagnetic radiation so that the specific absorption rate (SAR) of the mobile communication device is reduced during body worn use of the mobile communication device. 4. The holder as claimed in claim 2, wherein the holder further comprises an attachment to couple the holder to the user. 5. The holder as claimed in claim 1, wherein the pouch comprises an outer surface and an inner surface, the patch being attached to the inner surface so that the patch is held within the pouch. 6. The holder as claimed in claim 1, wherein the pouch comprises an outer cover and an inner liner, the patch being held between the outer cover and the inner liner. 7. The holder as claimed in claim 1, wherein the mobile communication device comprises a keypad and display, and wherein the receptacle comprises a case for removably substantially enclosing the mobile communication device when the mobile communication device is received in the receptacle, the case providing access to at the keypad and display while the mobile communication device. 8. The holder as claimed in claim 7, wherein the case comprises an outer surface and an inner surface, the patch being attached to the inner surface so that the patch is held within the case. 9. The holder as claimed in claim 7, wherein the case comprises an outer cover and an inner liner, the patch being held between the outer cover and the inner liner. 10. The holder as claimed in claim 1, wherein the receptacle comprises a holster for removably receiving the mobile communication device. 11. The holder as claimed in claim 10, wherein the holster comprises a wall portion disposed between the mobile communication device and a body of a user of the mobile communication device, the wall portion holding the patch between the body of the user and the region of substantially maximum elevated electromagnetic radiation. 12. The holder as claimed in claim 1, wherein the patch comprises an electromagnetic field reducing material. 13. The holder as claimed in claim 12, wherein the electromagnetic field reducing material absorbs electromagnetic radiation from the region. 14. The holder as claimed in claim 12, wherein the electromagnetic field reducing material comprises a dielectric material. 15. The holder as claimed in claim 12, wherein the electromagnetic field reducing material comprises a metallic material. 16. The holder as claimed in claim 15, wherein the mobile communication device includes an antenna and the metallic material detunes the antenna. 17. The holder as claimed in claim 12, wherein the electromagnetic field reducing material comprises a magnetic material. 18. A holder for a mobile communication device generating at least a first region of substantially maximum elevated electromagnetic radiation and a second region of substantially maximum elevated electromagnetic radiation, the elevation of electromagnetic radiation of the first region being greater than the elevation of electromagnetic radiation emitted by the second region, the holder comprising: a receptacle for receiving and holding the mobile communication device, said receptacle including a first wall, second wall and third wall; and a first patch held in proximity to the first region by the receptacle while the mobile communication device is received in the receptacle for attenuating electromagnetic radiation emitted from the first region, said first patch being located only in a portion of said first wall of said receptacle, the first patch comprising first electromagnetic field reducing material; a second patch held in proximity to the second region by the receptacle while the mobile communication device is received in the receptacle for attenuating electromagnetic radiation emitted from the second region, said second patch being located only in a portion of said first wall of said receptacle, the second patch comprising a second electromagnetic field reducing material, wherein the first patch and the second patch attenuate electromagnetic radiation from the mobile communication device so that the specific absorption rate (SAR) of the mobile communication device is reduced when the mobile communication device is received in the receptacle. 19. The holder as claimed in claim 18, wherein the receptacle is wearable by a user of the mobile communication device so that the mobile communication device is held adjacent to the body of the user for providing body worn use of the mobile communication device. 20. The holder as claimed in claim 19, wherein the receptacle holds the first patch between the body of the user and the first region of substantially maximum elevated electromagnetic radiation and holds the second patch between the body of the user and the second region of substantially maximum elevated electromagnetic radiation so that the specific absorption rate (SAR) of the mobile communication device is reduced during body worn use of the mobile communication device. 21.
