1. A wireless device comprising:
one or more heat spreaders;
one or more printed circuit boards (PCBs);
an antenna compliment ring comprising portions of multiple antennas; and
one or more compact spiraled slot antennas comprising a slot formed by coupling the one or more heat spreaders, the one or more PCBs, and the antenna compliment ring, wherein combination of the one or more heat spreaders, the one or more PCBs and the antenna compliment ring create the one or more compact spiraled slot antennas and enables current to flow around the slot of the one or more compact spiraled slot antennas and through the one or more PCBs to create an electric field, such that the one or more compact spiraled slot antennas is allowed to radiate, the one or more compact spiraled slot antennas having dimensions that are less than one quarter of a output wavelength, wherein the slot comprises of a plurality of lengths protruding in a plurality of planes.
