초록

Effect to altered geometry of a suggested defected ground structure(DGS) unit cell was investigated . And equivalent circuit model was extracted from the DGS unit cell A microstrip band Pass filter with DGS has been designed in this Paper. The BPF with DGS was fabricated and obtained experimental results with network analyzer HP8510C. Experimental results show the center frequency of 2.45GHz, the insertion loss of 0.85dB, and the 3-dB bandwidth of 470MHz (19.5%). The center frequency of BPF is 2.4GHz which is available for wireless LAN.
