摘要： A communication device (100) includes an RF (Radio Frequency) module (110), an antenna structure (120), a first switch element (150), a second switch element (170), a plurality of first impedance elements (160), and a plurality of second impedance elements (180). The antenna structure (120) is coupled to the RF module (110). The antenna structure (120) includes a first radiation element (130) and a second radiation element (140). The first switch element (150) is coupled to the first radiation element (130). The first switch element (150) is switchable between the first impedance elements (160). The second switch element (170) is coupled to the second radiation element (140). The second switch element (170) is switchable between the second impedance elements (180).
