An antenna adapted to operate in multiple frequency bands includes a first conductive loop element having a commonly driven electrical connection at both ends. The first conductive element is resonant at a first frequency. An electrical feed point is located at the commonly driven electrical connection of the first conductive element. A second conductive element includes a straight portion and a helical portion. The straight portion being is coupled to the electrical feed point and the helical portion being is located distally from the feed point. The second conductive element being resonant at a second frequency. This commonly driven loop provides for a wider bandwidth and allows for a more compact multi-band antenna.
