Abstract
A dual-band antenna for communication device includes a first dipole antenna, a second dipole antenna and a coaxial feed line. The first dipole antenna includes a first radiating element disposed at a first plane and a first ground portion disposed at a second plane. The second dipole antenna includes a second radiating element disposed at a first plane and a second ground portion disposed at a second plane. The feed line includes an inner conductor electrically connecting to the first and second radiating elements and an outer conductor electrically connecting to the first and second ground portions. The first and second radiating elements both further include a compensating portion for improving radiating patterns of the first and second dipole antennas and a broadband portion for increasing frequency bands of the first and second dipole antennas.
