Application Status of Left-and Right-Handed Transmission Lines in Miniaturized Antenna Units

摘要

For the dual-/multi-frequency characteristics, the wideband phase-shifting characteristics, the miniaturization characteristics, and the zero-/ negative-order resonance characteristics of the right- and left-handed transmission lines, based on the miniaturization characteristics of the right- and left-handed transmission lines, the phase compensation of the left- and right-handed structures can be utilized to achieve miniaturization of the antenna. This paper summarizes the application of left- and right-handed transmission lines and "block" left-handed materials in small antenna units.
