Multiple band chassis antenna

摘要

A wireless device including a conductive chassis and a conductive coupling element is provided. The conductive coupling element may be connected to the conductive chassis and may cooperate with the conductive chassis to form a slit. An elongate feed element may be disposed within the slit. The coupling element may be configured to activate at least a portion of the conductive chassis to enable the chassis to operate as an antenna.

1. A wireless device, comprising:
a conductive chassis; a counterpoise galvanically connected to the conductive chassis; a conductive coupling element, the conductive coupling element comprising a first generally linear portion having a length, a first end and a second end, a second generally linear portion connected to the first generally linear portion towards the second end of the first generally linear portion, the second generally linear portion being substantially perpendicular to the first generally linear portion and continuous therewith and a third portion substantially perpendicular to and continuous with the second generally linear portion, the third portion forming a part of the conductive chassis, the first generally linear portion of the conductive coupling element and the conductive chassis cooperating to form a slit therebetween, the first, second and third portions of the conductive coupling element defining a slot operating as a slot antenna; a connector connecting the counterpoise to the first generally linear portion, the connector generally located at a first end of the first generally linear portion; and an elongated feed element disposed in the slit between the coupling element and the chassis, the elongated feed element being generally parallel to the length of the first generally linear portion of the conductive coupling element and being spaced apart therefrom such that the elongated feed element is not galvanically connected to the conductive coupling element, the elongated feed element generally entering the slit towards the second end of the first generally linear portion, wherein the coupling element is configured to activate at least a portion of the conductive chassis to enable the chassis to operate as an antenna in at least one frequency band.
