First Claim
1. 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.

Abstract
A wireless communications terminal can include 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 to at least partially enclose a display device and a user input interface. 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 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. The first radiator line resonates in a first frequency range responsive to first electromagnetic radiation coupled to the feed and ground nodes. A second radiator line is connected to the feed node and extends away from an adjacent portion of the first radiator line, and resonates in a second frequency range responsive to second electromagnetic radiation coupled to the feed and ground nodes. A third radiator line is connected to the first radiator line at a branch node that is spaced apart from the feed node and the ground node, and extends away from an adjacent portion of the first radiator line and resonates in a third frequency range responsive to third electromagnetic radiation coupled to the feed and ground nodes.
