Electronic device antennas having isolation elements

Abstract:

An electronic device may include an antenna and peripheral conductive housing structures. A dielectric gap may divide the peripheral conductive housing structures into first and second segments. The first and second segments may be separated from the antenna ground by respective first and second slots and may be fed using respective first and second feeds. An antenna isolation element may be coupled to the antenna ground and may separate the first slot element from the second slot element. The antenna isolation element may include a metal strip having an end coupled to the antenna ground and an opposing tip that extends into the dielectric gap. The antenna isolation element may electromagnetically isolate first radio-frequency signals conveyed by the first antenna feed in a cellular midband from second radio-frequency signals conveyed by the second antenna feed in a cellular high band.
