Abstract:
1. An apparatus comprising: a portable communication device, wherein said portable communication device is a handset; at least a first single antenna, the first single antenna being included entirely within the handset; said first single antenna operates at multiple frequency bands, and wherein at least two of said frequency bands are non-overlapping cellular telephone system frequency bands within the 800 MHz-3600 MHz frequency range; said first single antenna comprising an element that radiates and receives electromagnetic waves, the element having a perimeter that is shaped as a multi-segment, irregular curve; said multi-segment, irregular curve comprises at least ten connected segments, each segment is shorter than one tenth of at least one operating free-space wavelength of the antenna; said multi-segment, irregular curve is shaped so that an arrangement of the segments of the multi-segment, irregular curve are not self-similar with respect to the entire multi-segment, irregular curve; and the first single antenna simultaneously receives electromagnetic waves within at least two of the frequency bands in the 800MHz-3600MHz frequency range.
