Decoupling apparatus, a radiation unit and antenna

Abstract

In one embodiment, the decoupling apparatus includes a conductive body adapted to be arranged in the antenna to act as a radiation part of the antenna for transmission of electromagnetic waves with a frequency; and at least one slot formed on the conductive body, wherein the at least one slot comprises a dividing part extending to an edge of the conductive body to divide the edge and an intersecting part intersecting with the dividing part. With the radiation part including the decoupling apparatus, the different band radiation units do not need to be far away from each other to obtain good performance.
