Two-shot knuckles for coupling electrically isolated sections of an electronic device and methods for making the same

An outer periphery antenna assembly for a mobile computing device, comprising:

• a conductive antenna section having:
• a straight portion;
• a curved portion connected to the straight portion;
• and
• a first coupling structure on a first surface of the curved portion;
• a conductive section having a second coupling structure on a second surface;
• and
• a coupling section formed of an insulating material that directly contacts and at least partially encapsulates the first and second coupling structures to:
• physically couple the conductive antenna section and the conductive section such that the straight portion is perpendicular to the conductive section;
• and
• electrically isolate the conductive antenna section from the conductive section, the coupling section being electrically isolated from the first and second coupling structures.

An antenna assembly for a mobile computing device, comprising:

• an antenna that functions as an external surface of the mobile computing device having a first protrusion projecting therefrom;
• a conductive structure having a second protrusion projecting therefrom;
• and
• a coupler formed of an insulating material that directly contacts, physically couples the antenna and the conductive structure, and electrically isolates the antenna from the conductive structure by at least partially enveloping the first and second protrusions, the coupler being electrically isolated from the first and second protrusions.
