- Abstract
A novel magneto-electro-dielectric waveguided metamaterial (MED-WG-MTM) that the effective permeability εeff is changed obviously with the decrease of substrate's thickness is proposed. The proposed MTM can be used to simultaneously achieve the miniaturization and ultra-thin profile of overall antenna. Then, for demonstrated the characteristic, a coplanar-waveguide (CPW)-fed antenna by loading the proposed MTM is designed, fabricated, and measured. The measured result shows that the S11 less than -10 dB is from 1.48 to 5.08 GHz (109.7% bandwidth) and 72% miniaturization is achieved. The results between simulation and measurement coincide well. The thickness of the overall antenna is only 0.003λmax, which is smallest compared with the reported ones. (λmax is the wavelength at the lowest operating frequency).
