ABSTRACT:
According to one embodiment of the present invention, a dipole antenna capable of supporting multi-band communications, includes a first portion of the antenna in a folded structure, a second portion of the antenna that includes a first coupling pad and a second coupling pad physically separated by a distance, and a current path along the first portion of the antenna and the second portion of the antenna, wherein a first portion of the current path that includes the first coupling pad and the second coupling pad is configured to introduce a slow wave effect if electric current flows through the first portion of the current path.
