Abstract
Small antennas for internal mounting within wireless communicators, such as radiotelephones, that can operate within multiple frequency bands, including low frequency bands are provided. A planar radiating element overlies a pair of adjacent, spaced-apart, substantially parallel conductive strips that are electrically connected to ground. The conductive strips are configured to parasitically couple with the radiating element. The planar radiating element includes a first meandering segment and a second meandering segment that is a mirror image of the first meandering segment. The first meandering segment includes a set of periodically spaced-apart planar undulations, such as U-shaped portions, and the second meandering segment includes a corresponding set of periodically spaced-apart planar undulations. The first and second meandering segments are connected together in opposing relationship therewith to form a continuous, conductive loop.
