    摘要: An antenna device includes a differential-line, a first metal and a second metal. The differential-line includes a first line and a second line. The first metal and second metal are coupled to the first line and second line respectively. The first metal and second metal have different shapes and/or different sizes. The first metal and second metal form symmetric or asymmetric dipole. The first metal and second metal can be disposed on the same plane or different planes, can be electrically insulated and can have a first slot and a second slot respectively. The antenna device can further include a base coupled to the first line and second line. The base can be a daughter board having a front-end module or not. The IC package in daughter board can have different sizes. The daughter board can be offset by different distances and can be coupled to a mother board.
