Electronic device antennas having multiple signal feed terminals

An electronic device comprising:

• a housing having peripheral conductive structures;
• a dielectric-filled gap in the peripheral conductive structures that divides the peripheral conductive structures into first and second segments;
• an antenna ground;
• a first slot that separates the antenna ground from the first segment;
• a second slot that extends from an end of the first slot beyond an edge of the dielectric-filled gap in the peripheral conductive structures, wherein the second slot has edges defined by the antenna ground and the second segment of the peripheral conductive structures;
• and
• an antenna formed from the antenna ground, the first slot, the second slot, the first segment, and the second segment, wherein the antenna comprises an antenna feed having a ground antenna feed terminal coupled to the antenna ground, a first positive antenna feed terminal coupled to the first segment, and a second positive antenna feed terminal coupled to the second segment.

An electronic device comprising:
