Abstract

The present application provides a handheld wireless communication device. The handheld wireless communication device includes a two part housing having an upper housing and a lower housing, the upper housing and the lower housing being rotatably coupled together via a hinge. The upper housing and the lower housing through a relative movement via the hinge can transition between an opened position and a closed position. The lower housing has a first conductor including one or more tuned structures and has a second conductor including one or more tuned structures, where each of the tuned structures of the first conductor and the second conductor are adapted for at least one of transmitting or receiving electromagnetic energy having a respective predefined range of frequencies in support of wireless communications. The first conductor and the second conductor in a spaced apart fashion relative to each other are located proximate a first side edge of the lower housing, where the first side edge is opposite a second side edge of the lower housing, where the second side edge of the lower housing is the side edge of the lower housing, which is most directly coupled to the upper housing via the hinge.

First claim

What is claimed is:

1. A handheld wireless communication device comprising:
a two part housing including an upper housing and a lower housing, the upper housing and the lower housing being rotatably coupled together via a hinge, wherein the upper housing and the lower housing through a relative movement via the hinge can transition between an opened position and a closed position;
wherein the lower housing includes a first conductor including one or more tuned structures and a second conductor including one or more tuned structures, each of the tuned structures of the first conductor and the second conductor being adapted for at least one of transmitting or receiving electromagnetic energy having a respective predefined range of frequencies in support of wireless communications;
wherein the first conductor and the second conductor in a spaced apart fashion relative to each other are located proximate a first side edge of the lower housing, where the first side edge is opposite a second side edge of the lower housing, the second side edge of the lower housing being the side edge of the lower housing, which is most directly coupled to the upper housing via the hinge;
wherein the first conductor and the second conductor have a respective signal feed point, and wherein the respective signal feed points of the first conductor and the second conductor are each coupled to one or more of a transceiver, a transmitter, and a receiver; and
wherein the one or more tuned structures of each of the first conductor and the second conductor includes a pair of branches that extend from each of the respective signal feed points.

2. The handheld wireless communication device of claim 1 , wherein when in the opened position, the upper housing and the lower housing extend in respective directions away from the hinge in substantially opposite directions.

3. The handheld wireless communication device of claim 1 , wherein when in the closed position, the upper housing and the lower housing each extend from the hinge in a same or substantially similar direction.

4. The handheld wireless communication device of claim 3 , wherein when in the closed position, a front facing of the upper housing is rotated so as to be proximate to and overlap at least a portion of a front facing of the lower housing.

5. The handheld wireless communication device of claim 4 , further comprising a bendable display that extends across at least portions of the front facing of the upper housing, the hinge, and the front facing of the lower housing.

6. The handheld wireless communication device of claim 4 , wherein when in the closed position, the lower housing includes a portion that is not overlapped by the upper housing, and wherein the not overlapped by the upper housing portion of the lower housing is proximate the first side edge of the lower housing and has an expanded thickness.

7. The handheld wireless communication device of claim 6 , wherein the first conductor and the second conductor are included in the expanded thickness of the lower housing.

8. The handheld wireless communication device of claim 1 , wherein a first one of the pair of branches for each of the first conductor and the second conductor support a communication of electromagnetic signals in a predesignated low band of operation of a first cellular standard.

9. The handheld wireless communication device of claim 8 , wherein the first one of the pair of branches for each of the first conductor and the second conductor, together, support received diversity for the predesignated low band of operation of the first cellular standard.

10. The handheld wireless communication device of claim 8 , wherein the upper housing, the lower housing, and the hinge of the two-part housing, each include conductive portions that together serve as the ground for the first one of the pair of branches for the first conductor and the second conductor, which support the communication of electromagnetic signals in the predesignated low band of operation of the first cellular standard.

11. The handheld wireless communication device of claim 1 , wherein a second one of the pair of branches for each of the first conductor and the second conductor support a communication of electromagnetic signals in a predesignated mid band of operation of a first cellular standard.

12. The handheld wireless communication device of claim 11 , wherein the second one of the pair of branches for each of the first conductor and the second conductor, together, support received diversity for the predesignated mid band of operation of the first cellular standard.

13. The handheld wireless communication device of claim 1 , wherein the first conductor includes a grounded parasitically coupled tuned structure, which supports a communication of electromagnetic signals in a predesignated high band of operation of a first cellular standard.

14. The handheld wireless communication device of claim 1 , wherein the first conductor includes a floating parasitically coupled tuned structure, which supports a communication of electromagnetic signals in a global positioning system.

15. The handheld wireless communication device of claim 1 , wherein the second conductor includes a grounded parasitically coupled tuned structure, which supports a communication of electromagnetic signals in a wireless internet protocol standard.

16. The handheld wireless communication device of claim 1 , wherein the first conductor includes a grounded parasitically coupled tuned structure and a floating parasitically coupled tuned structure, and the second conductor includes a grounded parasitically coupled tuned structure.

17. A handheld wireless communication device comprising:
a two part housing including an upper housing and a lower housing, the upper housing and the lower housing being rotatably coupled together via a hinge, wherein the upper housing and the lower housing through a relative movement via the hinge can transition between an opened position and a closed position;
wherein the lower housing includes a first conductor including one or more tuned structures and a second conductor including one or more tuned structures, each of the tuned structures of the first conductor and the second conductor being adapted for at least one of transmitting or receiving electromagnetic energy having a respective predefined range of frequencies in support of wireless communications;
wherein the first conductor and the second conductor in a spaced apart fashion relative to each other are located proximate a first side edge of the lower housing, where the first side edge is opposite a second side edge of the lower housing, the second side edge of the lower housing being the side edge of the lower housing, which is most directly coupled to the upper housing via the hinge;
wherein the first conductor and the second conductor have a respective signal feed point, and wherein the respective signal feed points of the first conductor and the second conductor are each coupled to one or more of a transceiver, a transmitter, and a receiver; and
wherein the respective signal feed points of the first conductor and the second conductor are each coupled to the one or more of the transceiver, the transmitter, and the receiver via a switch, wherein the switch can respectively reverse a particular signal being applied to each of the respective signal feed points of the first conductor and the second conductor.
