Application Status of Left and Right Handed Transmission Lines in Dual/Multi-Band Antenna Units

摘要

The advent of dual/multi-band antennas has met the need for diversification of modern wireless communication functions. The left and right hand transmission lines have positive, zero and negative order resonant frequencies, and based on this characteristic, dual/multiple frequency antennas can be realized. This paper summarizes the application of the left and right hand transmission lines in the dual/multi-frequency antenna unit.
