Electronic Device with Switchable Antenna Loop Path

An electronic device comprising:

• peripheral conductive housing structures having a dielectric-filled gap that divides the peripheral conductive housing structures into a first segment and a second segment;
• and
• an antenna having
• an antenna ground separated from the first and second segments by a slot,
• a resonating element arm formed from the first segment, and
• a switchable loop path that includes a first conductive path coupled across the dielectric-filled gap, a second conductive path coupled across the slot, a third conductive path coupled across the slot, and a portion of the antenna ground extending from the second conductive path to the third conductive path.

An antenna comprising:

• an antenna ground;
• a resonating element arm;
• a feed terminal coupled to the resonating element arm;
• a conductive structure separated from the resonating element arm by a gap;
• a tuning element having a first terminal, a second terminal, and a third terminal, the first terminal being coupled to the conductive structure;
• a first conductive path that couples the first terminal to the resonating element arm;
• a second conductive path that couples the resonating element arm to the antenna ground;
• and
• a third conductive path that couples the antenna ground to the third terminal.
