Negative impedance elements and their applications in antenna miniaturization

Electrically small antennas present high-Q impedance characterized by large reactance and small radiation resistance. For such antennas, the effectiveness of passive matching is severely limited by gain-bandwidth theory, which predicts narrow bandwidths and/or poor gain. It is possible in theory to...
