A design and simulation for microstrip line filter with semicircle defected ground structure has been researched. In this paper, simulated soft (Ansoft HFSS V.6.0) used to be simulated the frequency response under different parameters such as dimensions, amounts of SDGS.The results show good performance of SDGS in high cut-off frequency, erase of harmonic frequency, smaller dimension. Final, a filter with4.4GHz center frequency,high Q-factor had been design and fabricated.
