Abstract
Planar inverted-F antennas having planar, non-linear conductive elements for use within communications devices, such as radiotelephones, are provided. Each planar, non-linear conductive element includes a first elongated segment and a second elongated segment in adjacent, co-planar, spaced-apart relationship with each other. A U-shaped intermediate segment electrically connects the first and second elongated segments. A signal feed extends outwardly from the first segment and is configured to electrically connect with RF circuitry within a communications device. A ground feed also extends outwardly from the first segment adjacent the signal feed and is configured to electrically ground the non-linear conductive element to a ground plane.
