design of multiband antennas using a single radiator. The theoretical prediction of antenna resonances can be achieved based on an effective medium model. Theoretical results have been verified via numerical simulations and measurements, which are all in good agreement. Further works include the improvement of feeding structure to eliminate the spurious resonance and optimal design to suppress unwanted surface wave radiation. It is anticipated that the proposed layered EBG structure can be used as synthetic dielectric substrates for multiple-band antenna design. 4-7, 2005. 4. F. Yang and Y.
