Abstract
An electronic device comprises a housing, a printed circuit board and a first slot antenna. The housing includes a side wall and a bottom plate coupled to the side wall. The printed circuit board is positioned above the bottom plate and at least partially forms a ground plane. The first slot antenna transmits and/or receives a first wireless signal having a first frequency and is formed in part by a first portion of a circumference of the bottom plate and the ground plane of the printed circuit board. The first slot antenna is formed within a lower plane of the housing.
