An antenna 300, or a method of making an antenna, comprises first and second radiating elements 310, 320 which operate over different frequency bands. The said elements 310, 320 have a common structure and a common ground. The first and second radiating elements 310, 320 are arranged to operate in receive and transmit modes independently and simultaneously. A conductive metal strip 332 may be part of the common antenna ground structure with mounting tabs 342, 344 located at each end of an elongate antenna structure to provide electrical and mechanical connections. The said tabs 342, 344 may each include a screw hole 346, 348. The common ground structure may include a flexible conductive foil. The first and second radiating elements 310, 320 may each have a respective feed point 312, 314. The antenna 300 may be used in a portable electronic information handling system (IHS) where the common ground is located between the antenna, a processor and a radio device. The antenna 300 provides a cheap compact multiple frequency band antenna which can operate in different wireless communication standards and may be located in the frame of a display. |
