Abstract
Inductively coupled antennas and methods of designing the same are disclosed. Electrically small antennas having relatively high efficiency and relatively broad bandwidth may be formed by inductively coupling an antenna loop to at least one antenna winding. Such antennas may be substantially planar. Various operating characteristics of such antennas may be adjustable by and/or dependent upon the strength of the inductive coupling between an antenna winding and an antenna loop.
