Abstract

A mobile device comprises a main compartment, a flip cover coupled to the main compartment, wherein the main compartment includes a Radio Frequency (RF) feed and ground, and wherein the flip cover includes at least one multiband antenna system in communication with the RF feed and ground, the antenna operating in at least one television broadcast band.

Claims

1. A mobile device comprising:

a main compartment;

a flip cover coupled to the main compartment, wherein the main compartment includes a Radio Frequency (RF) feed and ground, and wherein said flip cover includes at least one multiband antenna system in communication with the RF feed and ground, said antenna operating in at least one television broadcast band.

2. The mobile device of claim 1 wherein said multiband antenna system operates in at least one frequency band below 300 MHz.

3. The mobile device of claim 2 wherein said multiband antenna system operates in the 174-240 MHz frequency band.

4. The mobile device of claim 1 wherein said multiband antenna system comprises:

a horizontal-vertical meander structure.

5. The mobile device of claim 1 wherein said multiband antenna system comprises:

at least one antenna element providing wireless computer network connectivity.

6. The mobile device of claim 5 wherein said wireless computer network connectivity includes connectivity according to IEEE 802.11.

7. The mobile device of claim 1 wherein said multiband antenna system comprises:

an antenna element with a plurality of slots therein.

8. The mobile device of claim 1 comprising:

a cable connecting said multi-band antenna system with said RF feed.

9. The mobile device of claim 1 comprising:

a wire trace, printed on a flexible film substrate, connecting said multi-band antenna system with said RF feed.

10. The mobile device of claim 1 wherein said multiband antenna system comprises:

a flexible film substrate.

11. The mobile device of claim 1 wherein said multiband antenna system comprises:

a connection to said ground.

12. The mobile device of claim 1 wherein said connection to said is selected from the list consisting of:

a wire trace, printed on a flexible film substrate; and

a cable.

13. The mobile device of claim 1 wherein said multiband antenna system comprises:

a plurality of diverse antenna elements providing Multiple Input Multiple Output (MIMO) performance.

14. A method for operating a mobile device, said mobile device including a cover, a main body portion with circuitry therein, and a television antenna system concealed within said cover and in communication with said circuitry in said main body portion, said method comprising:

opening said cover to reveal a screen of said mobile device and positioning said antenna in a generally vertical posture; and

interacting with said mobile device to cause said mobile device to receive television signals using said television antenna and to cause said mobile device to display visual output on said screen based on said received television signals.

15. The method of claim 14 further comprising:

interacting with said mobile device to cause said mobile device to transmit and receive communications with a wireless computer network.

16. The method of claim 15 wherein said mobile device and said wireless computer network communicate according to the IEEE 802.11 standard.

17. The method of claim 14 further comprising:

powering down said mobile device; and

closing said cover to conceal said screen.

18. A mobile television comprising:

a body portion, said body portion comprising;

a circuit board, including one or more RF modules to receive television signals;

circuits for demodulating said television signals; and

a screen for displaying visual output based upon said demodulated signals;

a hinged cover coupled to said body portion and concealing a television antenna therein, said television antenna in communication with said circuit board.

19. The mobile television of claim 18 wherein said hinged cover provides an illusion to a consumer that the mobile television does not include an external antenna.

20. The mobile television of claim 18 wherein said television antenna comprises a monopole antenna element.

21. The mobile television of claim 18 wherein said television antenna comprises a meander-line structure on a flexible film substrate.
