Abstract

A wireless communication device (200) comprising an antenna system is disclosed. The antenna system includes a first plate conductor (202) and a second plate conductor (204) that can interact capacitively. The first plate conductor (202) and the second plate conductor (204) have surfaces that are at least partially overlapping and are in close proximity to each other. The antenna system further includes one or more feed points (206). In some embodiments, the antenna system will include one or more localized complex impedances (802) coupled to at least one of the first plate conductor (202) and the second plate conductor (204) proximate a respective edge for modifying the corresponding electrical length. In further embodiments, at least one of the first plate conductor (202) and the second plate conductor (204) will form at least a portion of the external housing of the wireless communication device (200).
