Abstract
Dual-band antennas include first and second radiating elements configured to be enclosed within a radiotelephone between a keypad and a top housing and to occupy available space existing around the perimeter of the keypad and/or between the keys of a keypad. First and second coplanar radiating elements are maintained in adjacent spaced-apart relationship with a circuit board underlying the keypad. The underlying circuit board serves as a ground plane for directing radiation from the antenna outwardly in a direction normal to the circuit board.
