Isolation of watch housing and antenna using a molded cover

A wrist-worn electronic device comprising:

• a lower housing including a molded cover and an outer portion, the molded cover including an upper portion composed of an electrically conductive material and a lower portion composed of an electrically non-conductive material, the upper portion having an upper surface having a first electrical ground location and a second electrical ground location;
• an upper housing opposing the molded cover of the lower housing, the upper housing including a bezel formed of an electrically conductive material, the bezel having a lower surface corresponding to an upper surface of the molded cover and a third electrical ground location and a fourth electrical ground location electrically coupled with the first electrical ground location and the second electrical ground location on the upper surface of the molded cover, respectively;
• an electrically non-conductive element positioned between the lower surface of the bezel and the upper surface of the molded cover;
• a first antenna configured to wirelessly receive a first electronic signal, the first antenna formed by a first nonconductive slot formed between a first portion of the lower surface of the bezel along a circumference of the bezel between the third electrical ground location and the fourth electrical ground location, a first portion of the upper surface of the molded cover along a circumference of the molded cover corresponding to the first portion of the lower surface of the bezel, and two electrical ground contacts each electrically coupling the first electrical ground location and the second electrical ground location on the upper surface of the molded cover with the third electrical ground location and the fourth electrical ground location on the lower surface of the bezel, respectively, the height of the first nonconductive slot corresponding to a height of the electrically nonconductive element;
• and
• a location determining element electrically coupled with the first antenna, the location determining element configured to receive the first electronic signal from the first antenna and determine a current geolocation of the electronic device based on the first electronic signal;
• wherein the lower portion of the molded cover is a composite and substantially electrically shields the first antenna from the outer portion of the lower housing;
• and
• wherein the lower housing includes a side wall that encloses the molded cover.
