Abstract: An electronic device 10, such as a cellular mobile phone, has an integrated hybrid multi-band antenna with a resonant element arm 108 (such as an inverted-F element) formed from conductive edges16 of a housing 12, which may be segmented by gaps 18(1,2). An opening separates the element arm 108 from a groundplane 104. An elongate conductive portion 142(1), which may extend from the groundplane 104, is located within the opening, forming an open slot with the groundplane 104. In embodiments, first and second conductive portions 142(1,2) bisect a U-shaped opening; and first and second antenna feeds F(1,2) are coupled between first and second conductive members 142(1,2) and the element arm 180. A transmission line may extend along conductive members 142(1,2), between radiofrequency transceiver circuitry 90 and antenna feeds F(1,2). Tuneable and fixed inductors 132, 134 may be coupled across a slot formed between a conductive member and the element arm.
