A shaped antenna element that radically reduces the physical size needed for
resonance
without the use of lossy loading elements, while at the same time allowing direct
connection to a coaxial feeder. The element is composed of at least two sub-elements
in close proximity to each other, coupled electrically to each other such that
the radiation resistance of the composite element is increased substantially. The
composite element can be used either as an antenna or part of an antenna that consists
of multiple such elements in order to provide increased directivity.
