Narrow bezel multiband antenna suitable for a tablet or laptop computer

Abstract

There is disclosed an antenna arrangement for a portable electronic device, comprising: a ground plane having an edge; and arranged along the edge, in sequence, a feed section, a grounded coupling section, and an extended coupling section. The feed section comprises an RF feed on the ground plane and a feed line extending from the RF feed having a first portion extending substantially perpendicularly from the edge of the ground plane, and a second portion extending from an end of the first portion, substantially parallel to the edge of the ground plane, in a direction away from the grounded coupling section. The grounded coupling section comprises a first conductive element extending substantially parallel to the edge of the ground plane and arranged to overlap or run adjacent to at least a part of the second portion of the feed line of the feed section, and a conductive member to connect the first conductive element to the ground plane. The extended coupling section comprises a conductive meander line extending generally parallel to the edge of the ground plane, one end of the conductive meander line being connected to or configured to couple with a portion of the grounded coupling section, the other end of the conductive meander line being connected to a second conductive element extending substantially parallel to the edge of the ground plane.
