1-16. (canceled)
A wireless device comprising:
- a non-conductive substrate;
- a ground plane located on the non-conductive substrate;
- a element for coupling having a first portion and a second portion, the first portion being located in proximity to an edge of the ground plane;
- a feed arm located in proximity to the edge of the ground plane and the first portion of the element for coupling;
- wherein the edge of the ground plane, the first portion of the element for coupling, and the feed arm are configured to cooperate together to function as a transmission line when supplied with a radiofrequency signal, and wherein the transmission line is configured to feed the radiofrequency signal to the second portion of the element for coupling.
