Abstract

A wireless communications card for use with an electronic device includes a frame and an antenna system. The frame is configured for removable installation in the electronic device. The antenna system includes first and second antennas each integral with the frame. At least one of the first and second antennas is selectively movable relative to the other between a first antenna configuration and a second antenna configuration.

Claims

1. A wireless communications card for use with an electronic device, the wireless communications card comprising:

a frame configured for removable installation in the electronic device; and

an antenna system including first and second antennas each integral with the frame, wherein at least one of the first and second antennas is selectively movable relative to the other between a first antenna configuration and a second antenna configuration.

2. The wireless communications card of claim 1 wherein the first antenna is internal to the frame and the second antenna is mounted on an extension member that is movably mounted on the frame such that the extension member and the second antenna can be selectively moved between a retracted position adjacent the frame and a second position extended from the frame.

3. The wireless communications card of claim 2 wherein the extension member is pivotally mounted on the frame for movement between the retracted and extended positions.

4. The wireless communications card of claim 2 wherein, when the extension member is in the retracted position, the extension member and the second antenna are disposed within the frame.

5. The wireless communications card of claim 2 including at least one switch operative to communicatively connect the second antenna to an associated antenna circuit when the extension member is in the extended position and to disconnect the second antenna from the associated antenna circuit when the extension member is in the retracted position.

6. The wireless communications card of claim 5 wherein the at least one switch is operative to communicatively connect the second antenna to a second associated circuit when the extension member is in the retracted position.

7. The wireless communications card of claim 1 wherein movement of the antenna system from the first antenna configuration and the second antenna configuration switches the second antenna from a connection to a first associated antenna circuit to a second associated antenna circuit.

8. The wireless communications card of claim 7 wherein the first and second associated antenna circuits are alternative impedance matching networks.

9. The wireless communications card of claim 7 wherein the first and second associated antenna circuits are alternative radio frequency circuits.

10. The wireless communications card of claim 1 wherein, when the first and second antennas are in the second antenna configuration, the antenna system comprises a diversity antenna system wherein the first and second antennas have different dominant polarizations from one another.

11. The wireless communications card of claim 10 wherein, when the first and second antennas are in the first antenna configuration, the second antenna couples to the first antenna as a parasitic element to broaden a bandwidth of the antenna system.

12. The wireless communications card of claim 10 wherein, when the first and second antennas are in the first antenna configuration, the first antenna is communicatively connected to a first antenna circuit adapted to radiate and/or receive radio signals over a first frequency range and the second antenna is communicatively connected to a second antenna circuit adapted to radiate and/or receive radio signals over a second frequency range different from the first frequency range.

13. The wireless communications card of claim 10 wherein, when the first and second antennas are in the first antenna configuration, the second antenna is inactive.

14. The wireless communications card of claim 1 wherein, when the first and second antennas are in the second antenna configuration, the first antenna is communicatively connected to a first antenna circuit adapted to radiate and/or receive radio signals over a first frequency range and the second antenna is communicatively connected to a second antenna circuit adapted to radiate and/or receive radio signals over a second frequency range different from the first frequency range.

15. The wireless communications card of claim 14 wherein, when the first and second antennas are in the first antenna configuration, the second antenna couples to the first antenna as a parasitic element to broaden a bandwidth of the antenna system.

16. The wireless communications card of claim 14 wherein, when the first and second antennas are in the first antenna configuration, the first antenna is communicatively connected to a third antenna circuit adapted to radiate and/or receive radio signals over a third frequency range different from the first and second frequency ranges.

17. The wireless communications card of claim 14 wherein, when the first and second antennas are in the first antenna configuration, the second antenna is inactive.

18. The wireless communications card of claim 1 wherein, when the first and second antennas are in the second antenna configuration, the second antenna is communicatively connected to an associated active antenna circuit and the first antenna is inactive.

19. The wireless communications card of claim 18 wherein, when the first and second antennas are in the first antenna configuration, the second antenna couples to the first antenna as a parasitic element to broaden a bandwidth of the antenna system.

20. The wireless communications card of claim 18 wherein, when the first and second antennas are in the first antenna configuration, the first antenna is communicatively connected to a first antenna circuit adapted to radiate and/or receive radio signals over a first frequency range and the second antenna is communicatively connected to a second antenna circuit adapted to radiate and/or receive radio signals over a second frequency range different from the first frequency range.

21. The wireless communications card of claim 18 wherein, when the first and second antennas are in the first antenna configuration, the second antenna is inactive.

22. The wireless communications card of claim 1 wherein the wireless communications card is at least one of a wireless communications PC Card and a wireless communications ExpressCard.

23. A mobile wireless communications terminal comprising:

a housing; and

an antenna system including first and second antennas each integral with the housing, wherein at least one of the first and second antennas is selectively movable relative to the other between a first antenna configuration and a second antenna configuration.
