Abstract

A housing includes a metal base and a non-conductive member. The metal base has an internal surface and a plurality of gap. The non-conductive member covers at least a portion of the internal surface of the metal base, and the non-conductive member is formed on the bottom of the at least one gap. The metal base is spaced by the gaps to form a plurality of metal sheets and at least one main body. Each gap is completely filled with one dielectric member. The metal sheets and the at least one main body are all bonded with the dielectric member and are electrically isolated with each other.
