Microstrip Balun Design Based on Metamaterial

Article Preview

Abstract:

Proposed of a model of microstrip balun based on metamaterial ,it uses the unique aspect of negative dielectric constant and negative magnetic permeability of metamaterial in the microwave , and designs the dielectric substrate , based on which we constructed a microstrip balun which can translate unbalanced 50 ohm signal to 120 ohm balanced .Simulation results show that it can perform well at reducing the size of balun , at the return loss (s11) ,insertion loss (s21) from 2G to 6G. As well as it can effectively meet the two-ports phase difference about 180 degrees.
