Abstract

An electronic device may be provided with wireless circuitry and a housing with upper and lower ends. The lower end may include first and second open slot antennas that are directly fed by respective feeds and that radiate in a cellular ultra-high band. The lower end may also include first and second inverted-F antennas. The upper end may include third and fourth inverted-F antennas. The first inverted-F antenna may have a first feed that conveys currents below 2700 MHz and a second feed that conveys antenna currents in the cellular ultra-high band, a wireless local area network band, and/or ultra-wideband frequency bands. If desired, the upper end may include a third open slot antenna that is directly fed by a corresponding antenna feed and that radiates in the cellular ultra-high band and/or in the ultra-wideband frequency bands.
