Abstract
An electronic device may be provided with a satellite positioning system slot antenna. The slot antenna may include a slot in a metal housing. The slot may be directly fed or indirectly fed. In indirectly fed configurations, the antenna may include a near-field-coupled antenna feed structure that is near-field coupled to the slot. The near-field-coupled antenna feed structure may be formed from a planar metal structure. The planar metal structure may be a metal patch that overlaps the slot and that has a leg that protrudes towards the metal housing. A positive antenna feed terminal may be coupled to the leg and a ground antenna feed terminal may be coupled to the metal housing.
