Recent technological advances and the size reduction of electronic circuits have changed the wireless communications and sensor network design specifications. In particular, they have exposed the need for electrically small antennas that are efficient and have significant bandwidths. The standard electrically small antenna designs are known to be inefficient due to the large reactance and small resistance, which leads to the poor match to a given source.
