Abstract
Various resonant modes of a multiresonant antenna structure share at least portions of the structure volume. The basic antenna element has a ground plane and a pair of spaced-apart conductors electrically connected to the ground plane. Additional elements are coupled to the basic element, such as by stacking, nesting or juxtaposition in an array. In this way, individual antenna structures share common elements and volumes, thereby increasing the ratio of relative bandwidth to volume.
