Abstract:
1. A multi frequency band antenna comprising: a low band portion tuned to a low frequency band; and a first high band portion tuned to a first high frequency band at higher frequencies than the low frequency band; wherein the low band portion and the first high band portion have: a common first grounding point; a common feeding point for feeding input signals to the antenna and for outputting signals from the antenna; and a first conductor portion forming part of the low band portion and of the first high band portion, the first conductor portion being electrically connected to the first grounding point and to the common feeding point, the antenna further comprising: a second high band portion, coupled to the first conductor portion and to a variable reactance, such that the second high band portion can be selectively tuned either to a second high frequency band or to a third high frequency band, each of the second and third high frequency bands being at a higher frequency than the low frequency band and different from the first high frequency band.
