Abstract
A frequency multiband antenna includes a photonic bandgap material having at least one band gap, one single periodicity defect of the bandgap material so as to produce several narrow bandwidths within the at least one band gap of the bandgap material, and an excitation device capable of transmitting and/or receiving electromagnetic waves within the narrow bandwidths.
