Methods for slot antenna design for wearable electronic devices and conductive housings

A device, comprising:

• a conductive housing having one or more interior surfaces;
• a power source;
• a conductive bracket having one or more edges or surfaces, the conductive bracket contained within and separate from the conductive housing, the one or more edges or surfaces of the conductive bracket and the one or more interior surfaces of the conductive housing forming a gap therebetween;
• a monopole antenna;
• an antenna matching circuit;
• a display within the conductive housing, wherein a dead band of the display overlaps with a dead band of the monopole antenna;
• and
• a printed circuit board (PCB) having one or more edges, the one or more edges of the PCB and the one or more interior surfaces of the conductive housing forming a second gap there between, a portion of the first gap forming a slot antenna, the PCB coupled to the monopole antenna through the antenna matching circuit and configured to drive a monopole radiator of the monopole antenna, wherein electromagnetic fields generated by the monopole antenna induce the slot antenna to transmit or receive radio frequency signals, further wherein the PCB and the conductive bracket form a back cavity therebetween, the back cavity comprising a dielectric gap and facilitating resonance of the slot antenna, and wherein the power source, the conductive bracket, the monopole antenna, the antenna matching circuit, and the PCB are within walls of the conductive housing.
