Abstract
A multiple frequency band antenna is disclosed involving a first resonant portion tuned to a low frequency band; a second resonant portion tuned to a first high frequency band at frequencies higher than the low frequency band; a third resonant portion tuned to a second high frequency band at frequencies higher than the low frequency band and substantially different from the first high frequency band; and a first conductor portion forming part of the first resonant portion and the second resonant portion, the first conductor portion having a grounding point, a feeding point for providing an input signal to at least one of the first resonant portion and the second resonant portion and for receiving an output signal from at least one of the first resonant portion and the second resonant portion, and a second conductor portion electrically connected to the feeding point wherein the third resonant portion is electrically connected to the second conductor portion.
