A case for a wireless tablet computer device includes a number of RF resonant loop elements and elongated RF director coupling strip elements mounted in the case and configured such that RF radiation is coupled from an internal antenna of the wireless device out of the device to the RF resonant and coupling elements. The case incorporates a cut-out section in a location leaving exposed a strip that covers an area proximate the internal antenna. The RF resonant loops and director coupling strip elements alternatively may be incorporated with the wireless tablet computer device itself.

1. An apparatus, comprising: a wireless communication device having a housing, an internal antenna and a coupling antenna, the housing having a first side and a second side opposite the first side, the internal antenna and the coupling antenna being operatively coupled when the wireless device is operational,the first side of the housing having a first portion and a second portion mutually exclusive from the first portion of the first side of the housing, the first portion of the first side of the housing having a material different from a material of the second portion of the first side of the housing,the internal antenna being disposed between the first portion of the first side of the housing and the second side of the housing, an interior of the housing being disposed between the coupling antenna and the second side of the housing. 2. The apparatus of claim 1, wherein the coupling antenna is disposed between the second portion of the first side of the housing and the second side of the housing. 3. The apparatus of claim 1, wherein the coupling antenna is disposed within the second portion of the first side of the housing. 4. The apparatus of claim 1, wherein the second portion of the first side of the housing is disposed between the coupling antenna and the second side of the housing. 5. The apparatus of claim 1, wherein the coupling antenna is formed on a flexible printed circuit board (FPCB). 6. The apparatus of claim 1, wherein the coupling antenna is disposed on a side of the housing, the side of the housing being disposed between the coupling antenna and the internal antenna. 7. The apparatus of claim 1, wherein the coupling antenna is disposed on a side of the housing, the coupling antenna being disposed between the side of the housing and the internal antenna. 8. An apparatus, comprising: an external case configured to be coupled to a wireless device having a housing separate from the external case,the external case having an antenna that operatively couples to an antenna of the wireless device when the external case is coupled to the wireless device and the wireless device is operational,the external case having a shape that covers a first portion of a side of the wireless device and exposes a second portion of the side of the wireless device mutually exclusive from the first portion of the wireless device, the second portion of the wireless device associated with a location of the antenna of the wireless device. 9. The apparatus of claim 8, wherein the external case having the shape such that the second portion of the side of the wireless device is exposed and overlays at least a portion of the antenna of the wireless device. 10. The apparatus of claim 8, wherein: the side of the wireless device is a first side of the wireless device,the external case having the shape such that (1) the second portion of the first side of the wireless device is exposed and (2) the antenna of the wireless device is disposed between the second portion of the first side of the wireless device and a second side of the wireless device opposite the first side of the wireless device. 11. The apparatus of claim 8, wherein the second portion of the wireless device is positioned relative to the antenna of the wireless device such that a total radiated power (TRP) of the antenna of the wireless device when the external case is coupled to the wireless device and the wireless device is operational substantially corresponds to a TRP of the antenna of the wireless device when the external case is not coupled to the wireless device and the wireless device is operational. 12. The apparatus of claim 8, wherein: a portion of the external case corresponding to the first portion of the side of the wireless device has a size along a dimension greater than a size along the dimension of a portion of the external case corresponding to the second portion of the side of the wireless device. 13. The apparatus of claim 8, wherein: the external case has an inner liner and an outer shell, a perimeter of the inner liner of the external case being less than a perimeter of the outer liner of the external case. 14. The apparatus of claim 8, wherein: the external case has an inner liner and an outer shell, the antenna of the external case being disposed between the inner line and the outer shell, the antenna of the external case overlaying the first portion of the side of the wireless device when the external case is coupled to the wireless device. 15. The apparatus of claim 8, wherein the antenna of the external case is formed on a flexible printed circuit board (FPCB). 16. An apparatus, comprising: an external case configured to be coupled to a wireless device having a housing separate from the external case,the external case having an antenna that operatively couples to an antenna of the wireless device when the external case is coupled to the wireless device and the wireless device is operational,the external case covering a first portion of a housing of the wireless device and not covering a second portion of the housing of the wireless device when the external case is coupled to the housing of the wireless device, the second portion of the housing of the wireless device being mutually exclusive from the first portion of the housing of the wireless device,the antenna of the external case being laterally offset from the second portion of the wireless device and the antenna of the wireless device when the external case is coupled to the wireless device. 17. The apparatus of claim 16, wherein the antenna of the external case overlays at least a portion of the first portion of the housing of the wireless device when the external case is coupled to the wireless device. 18. The apparatus of claim 16, wherein: the antenna of the external case overlays at least a portion of the first portion of the housing of the wireless device when the external case is coupled to the wireless devicethe antenna of the external case does not overlay at least a portion of the antenna of the wireless device and does not overlay the second portion of the wireless device when the external case is coupled to the wireless device. 19. The apparatus of claim 16, wherein: the antenna of the external case is formed on a flexible printed circuit board (FPCB),the FPCB overlays at least a portion of the first portion of the housing of the wireless device when the external case is coupled to the wireless devicethe FPCB does not overlay at least a portion of the antenna of the wireless device and does not overlay the second portion of the wireless device when the external case is coupled to the wireless device. 20. The apparatus of claim 16, wherein the external case is positioned relative to the wireless device when coupled together such that a total radiated power (TRP) of the antenna of the wireless device when the external case is coupled to the wireless device and the wireless device is operational substantially corresponds to a TRP of the antenna of the wireless device when the external case is not coupled to the wireless device and the wireless device is operational.
