First Claim
Patent Images
1. An electronic device, comprising:
- a metal housing that forms a ground plane, wherein a slot is formed in the ground plane, the slot has a bend, the metal housing has a planar rear wall and a sidewall that extends from the rear wall, the slot is formed in the rear wall and the sidewall, the slot extends from a first edge of the sidewall to an opposing second edge of the sidewall, and the slot has an opening along the second edge of the sidewall;
an indirectly fed slot antenna formed from the slot, the indirectly fed slot antenna comprising a near-field-coupled antenna feed structure that is formed from a planar metal structure that is near-field coupled to the slot;
a first tunable component coupled across the slot at a first side of the near-field-coupled antenna feed structure; and
a second tunable component coupled across the slot at a second side of the near-field coupled antenna feed structure.

Abstract
An electronic device may be provided with antennas. Antennas for the electronic device may be formed from slot antenna structures. A slot antenna structure may be formed from portions of a metal housing for an electronic device. The slots of the slot antenna structures may be indirectly fed to form first and second indirectly fed slot antennas. The first and second indirectly fed slot antennas may be formed from slots in a rear surface of an electronic device and a sidewall of the electronic device. The slots may have open ends along an edge of the sidewall and may have closed ends that face each other. A hybrid antenna may also be formed in the electronic device.

4. An electronic device, comprising:
-
a metal housing having at least first and second slots, wherein portions of the metal housing run along opposing sides of the first slot and portions of the metal housing run along opposing sides of the second slot, the first slot has a first segment, a second segment that extends substantially perpendicular to the first segment, and a third segment coupled between the first and second segments, the first and second segments have a first width, and the third segment has a second width that is greater than the first width; a first indirectly fed slot antenna formed from the first slot, wherein the first indirectly fed slot antenna comprises a first near-field coupled antenna feed structure having a first metal structure that overlaps the first slot and that is separated from the first slot; and a second indirectly fed slot antenna formed from the second slot, wherein the second indirectly fed slot antenna comprises a second near-field coupled antenna feed structure having a second metal structure that overlaps the second slot and that is separated from the second slot. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)

13. An electronic device, comprising:
-
a metal housing having a rear wall, a sidewall that extends from the rear wall, and first and second slots, wherein the first slot has an open end formed at a first edge of the sidewall and an opposing closed end formed in the rear wall, the second slot has an open end formed at the first edge of the sidewall and an opposing closed end formed in the rear wall, the first and second slots each extend from a second edge of the sidewall to the first edge of the sidewall, portions of the rear wall are on opposing sides of the first slot and at the closed end of the first slot, portions of the rear wall are on opposing sides of the second slot and at the closed end of the second slot, and the metal housing forms a ground plane; a first indirectly fed slot antenna formed from the first slot, wherein the first indirectly fed slot antenna is fed using a first antenna feed element; and a second indirectly fed slot antenna formed from the second slot, wherein the second indirectly fed slot antenna is fed using a second antenna feed element that is different from the first antenna feed element. - View Dependent Claims (14, 15, 16, 17)
