Patent ID: 8378899

Claim:
A wireless communications terminal comprising: a housing having an interior surface that is configured to enclose at least a controller circuit, a transceiver circuit, and a RF feed circuit and is configured to at least partially enclose a display device and a user input interface, wherein the housing extends between opposing top and bottom surfaces, between opposing first and second side surfaces, and between opposing front and back surfaces; a first radiator line that is connected on distal ends to a feed node and to a ground node and extends in a loop across at least a majority of a width of the housing between the first and second side surfaces, wherein the first radiator line is configured to resonate in a first frequency range responsive to first electromagnetic radiation coupled to the feed and ground nodes; a second radiator line that is connected to the feed node and extends away from an adjacent portion of the first radiator line, wherein the second radiator line is configured to resonate in a second frequency range responsive to second electromagnetic radiation coupled to the feed and ground nodes; and a third radiator line that is connected to the first radiator line at a branch node that is spaced apart from the feed node and the ground node, wherein the third radiator line extends away from an adjacent portion of the first radiator line and is configured to resonate in a third frequency range responsive to third electromagnetic radiation coupled to the feed and ground nodes, wherein the first, second, and third frequency ranges are different from one another, wherein: the first, second, and third radiator lines extend along a single flexible film surface; the first radiator line extends on the flexible film surface across the terminal and is fixedly attached to the top surface or the bottom surface; the second and third radiator lines extend on the flexible film surface along and are fixedly attached to at least one side surface of the housing; and the second and third radiator lines extend on the flexible film surface along and are fixedly attached to opposite side surfaces of the housing.
