摘要：
A multiband antenna in a wireless communication device includes a main antenna, a first parasitic portion, a second parasitic portion, a first switch, and a second switch, the first switch is used to control functioning of the first parasitic portion. The second switch is used to control functioning of the second parasitic portion. Therefore, the main antenna can resonate alone or in combination with the functioning first parasitic portion and/or the functioning second parasitic portion, the multiband antenna has different operating frequency bands and different operating SAR.
