    Abstract: A cavity-backed antenna 26, or an electronic device, comprises a cavity-backed resonant antenna element 70 where the cavity 72 is formed from a dielectric support structure 112 covered with a layer of conductive material 74, 76. The dielectric material may be a moulded plastic support structure 112 covered by a conductive metal such as copper or aluminium via any suitable deposition technique. The resonant antenna element 70 may take any form including one or more open and/or closed slot arrangements in a conductive plate, planar inverted-F antenna arrangements, patch antennas or various monopole and/or dipole printed antenna arrangements. The antenna may be arranged to operate in one or more different frequency bands. The cavity backed antenna 26 may be used in a housing associated with an electronic device such as a computer or a mobile phone. An antenna window may be provided in the said housing where the window may be formed by a region of dielectric material or from antenna window slots formed in a conductive member such as a conductive wall of the electronic device housing.

    Abstract: Electronic devices (10) may include radio-frequency transceiver circuitry (32) and antenna structures (34). The antenna structures (34) may include antenna resonating elements (60) such as dual-band antenna resonating elements that resonate in first and second communications bands. The antenna structures may also contain parasitic antenna elements (60) such as elements that are operative in only the first or second communications band and elements that are operative in both the first and second communications bands. The antenna resonating elements and parasitic elements may be mounted on a common dielectric carrier. The dielectric carrier may be mounted within a slot (56) or other opening in a conductive element. The conductive element may be formed from conductive housing structures in an electronic device such as a portable computer. The portable computer may have a clutch barrel (54) with a dielectric cover. The dielectric cover may overlap and cover the slot and the dielectric carrier.
