Abstract
A C-shaped dielectric substrate having a folded configuration includes opposite first and second spaced apart portions joined at respective adjacent end portions by a third portion. A continuous trace of conductive material, which serves as a radiating element, is disposed on the outer surfaces of the dielectric substrate first, second and third portions. The portion of the continuous radiating element disposed on the dielectric substrate first portion is configured to electrically couple with the portion of the continuous radiating element disposed on the dielectric substrate second portion such that at least two separate and distinct frequency bands are created.
