Abstract

A wireless device comprises a radiating system that comprises and a radiating structure that operates in at least two frequency regions. The radiating structure comprises: a ground plane layer having a first connection point; a single radiation booster having a first connection point; a radiofrequency system comprising a first input port, a plurality of external output ports, and a plurality of branches, at least some of the plurality of branches being connected to a common point connected to the first input port, wherein each of the plurality of external output ports provides operation in at least one of the at least two frequency regions of operation; and a first internal port defined between the first connection point of the radiation booster and the first connection point of the ground plane layer, the first internal port being connected to the first input port of the radiofrequency system.

First claim

What is claimed is:

1. A wireless device comprising a radiating system that comprises:
a radiating structure that operates in at least two frequency regions, the radiating structure comprising:
a ground plane layer;
a single radiation booster;
a first internal port defined between a connection point of the single radiation booster and a connection point of the ground plane layer; and
a radiofrequency system comprising: first and second external output ports each providing operation in at least one of the at least two frequency regions; a first signal path from a first signal path input port to the first external output port; a second signal path from a second signal path input port to the second external output port; and a first circuit having an input port connected to the first internal port of the radiating structure and an output port connected to the first signal path input port and to the second signal path input port.

2. The wireless device of claim 1 , wherein the radiofrequency system further comprises a third external output port.

3. The wireless device of claim 2 , wherein the radiofrequency system further comprises a switch.

4. The wireless device of claim 1 , wherein the radiofrequency system further comprises a fourth external output port.

5. The wireless device of claim 1 , further comprising a first reject-band filter disposed along the first signal path.

6. The wireless device of claim 5 , further comprising a second reject-band filter disposed along the second signal path.

7. The wireless device of claim 1 , wherein the radiofrequency system comprises a diplexer.

8. The wireless device of claim 7 , wherein the diplexer comprises a bank of filters.

9. The wireless device of claim 1 , wherein the radiofrequency system comprises at least one filtering circuit.

10. The wireless device of claim 9 , wherein the at least one filtering circuit comprises at least one reject-band filter.

11. The wireless device of claim 9 , wherein the at least one filtering circuit comprises at least two reject-band filters.

12. The wireless device of claim 1 , wherein the radiating structure further comprises a second internal port defined between a second connection point of the radiation booster and a second connection point of the ground plane layer.

13. The wireless device of claim 12 , wherein the second internal port is connected to a second input port of the radiofrequency system.

14. The wireless device of claim 1 , wherein the radiofrequency system comprises at least one matching network.

15. The wireless device of claim 14 , wherein the radiofrequency system further comprises at least as many matching networks as frequency regions of operation of the radiating system.

16. The wireless device of claim 1 , further comprising a processing module, a memory module, and a display and a communication module for tracking the position of the wireless device.

17. The wireless device of claim 1 , wherein the at least two frequency regions are frequency regions within which cellular communication standards operate.
