  • In this paper, designed and fabricated the 1.9GHz band isolator for wire-less communication base-stations. It was investigated that characteristics of insertion loss and return loss. The characteristic results of dual structure design showed values that insertion loss was about -40dB and return loss was about -23dB at 1.93$\sim$1.99GHz.
