ABSTRACT:
A dual-band antenna (1) includes a first antenna (2) and a second antenna (3). The first antenna includes a u-shaped first dipole half (11) and an n-shaped second dipole half (12). The first dipole half is disposed above the second dipole half with a space therebetween and the two dipole halves are mirror imaged. The second antenna includes a u-shaped third dipole half (21) and an n-shaped fourth dipole half (22). The first and the third dipole halves are crossly connected with each other at bottom. The second and the fourth dipole halves are crossly connected with each other at top.
