Antennas configured to be enclosed within a flip cover of a radiotelephone and to resonate in three frequency bands include a dielectric substrate having opposite first and second faces, and opposite first and second ends. A first radiating element is disposed on the first face adjacent the first end, and a second radiating element is disposed on the dielectric substrate second face adjacent the second end. Each radiating element tapers from a respective end of the substrate to a medial portion of a respective face. Each radiating element also includes a respective meandering electrically conductive path. |
