The miniaturization of transmission line (CRLH) structure；3rd class is to absorb antenna array with tradition metamaterial unit series resistor composition Meta Materials
Row, at present major part research concentrates on this, but current research be the most all in sub-wavelength unit series resistor by radio frequency energy
Amount absorbs, and in reality, we need to connect commutator or electric capacity, wireless energy is changed into direct current output or stores, because of
This above-mentioned work is closer to absorber based on Meta Materials.It addition, directly concatenate commutator or electric capacity at sub-wavelength unit,
Also can exist owing to input power is extremely low, the problem that conversion efficiency is low.4th class is the Super-material antenna using electric small-size
And organize battle array, but the electronically small antenna gain that worked is relatively low, and is operated in single-frequency or double frequency, and when organizing gust, unit interval is still limited
System is at about 0.5 λ, and overall dimensions is the biggest.
