Abstract:
1. A multiband antenna for a portable communication device, comprising: a first antenna unit for receiving and/or sending wireless signals; a second antenna unit connected to the first antenna unit for receiving and/or sending wireless signals; a third antenna unit connected to the first antenna unit for receiving and/or sending wireless signals; and a feed member electrically connected to the first antenna unit and the second antenna unit, wherein the feed member receives wireless signals and transmits the wireless signals through the first antenna, the second antenna unit and the third antenna unit to generate corresponding current paths, and the first antenna unit is located between the second antenna unit and the third antenna unit to isolate the second antenna unit and the third antenna unit to avoid coupling interference of their resonant frequencies; the first antenna unit, the second antenna unit and the feed member are coplanar, and the third antenna unit is perpendicular to the plane of the first antenna unit.
