Patent ID: 8736497

Claim:
A wireless device comprising: a radiating system configured to transmit and receive electromagnetic wave signals in a first frequency region and in a second frequency region, wherein the highest frequency of the first frequency region is lower than the lowest frequency of the second frequency region, the radiating system comprising: first and second external ports; a radiating structure comprising: a first radiation booster having a maximum size less than 1/30 times a free-space wavelength corresponding to the lowest frequency of the first frequency region; a second radiation booster having a maximum size less than 1/30 times the free-space wavelength corresponding to the lowest frequency of the first frequency region; a ground plane layer; a first internal port defined between a connection point of the first radiation booster and a connection point of the ground plane layer; and a second internal port defined between a connection point of the second radiation booster and a connection point of the ground plane layer; and a radiofrequency system comprising: a first port connected to the first internal port of the radiating structure; a second port connected to the second internal port of the radiating structure; a third port connected to the first external port of the radiating system; a fourth port connected to the second external port of the radiating system; a first matching network connected to the first port and configured to provide impedance matching within the first frequency region at the first external port; and a second matching network connected to the second port and configured to provide impedance matching within the second frequency region at the second external port.
