摘要： An electronic device may have an antenna that includes conductive antenna structures forming an antenna resonating element and an antenna ground. A band-stop filter may be coupled between first and second portions of the conductive structures. The band-stop filter may be formed from multiple series-connected resonant circuits. The band-stop filter and an impedance matching circuit may be coupled in series between the antenna resonating element and the antenna ground. The band-stop filter may be characterized by a stop band. The antenna may be configured to operate in a first communications band that is outside of the stop band and a second communications band that is covered by the stop band. The impedance matching circuit may be an adjustable circuit that is used to tune the antenna. The adjustable circuit may be a switch-based adjustable capacitor that is adjusted to tune the response of the antenna in the first communications band.

摘要： A display cover layer may be mounted in an electronic device housing using housing structures such as corner brackets. A slot antenna may be formed from a corner bracket opening, metal traces on a hollow plastic support structure, or other conductive structures. The slot antenna may have a main portion with opposing ends. An antenna feed may be located at one of the ends. The slot antenna may have a slot with one or more bends. The bends may provide the slot antenna with a C-shaped outline. A side branch slot may extend from the main portion of the slot at a location between the two bends. The presence of the side branch slot may enhance antenna bandwidth. A hollow enclosure may serve as an antenna support structure and as a speaker box enclosing a speaker driver. The antenna feed may be positioned so as to overlap the speaker driver.
