ABSTRACT:
A dual-band antenna (1) for communication device includes a first radiating element portion (10) operating at a first frequency band, a second radiating element portion (20) operating at a second frequency band, an L-shaped ground portion (40), a conductive connection (50) interconnecting the first and second radiating element portions (10, 20) with the ground portion (40) and a slot (101) served as an impedance transformer and positioned on the ground portion (40). The slot (101) is implemented as a capacitive load that eliminates the inductive part of the input impedance of the antenna, thereby the slot (101) can match the input impedance of the antenna with a feed line.
