A complete detailed theoretical analysis for the proposed filter is given using equivalent circuit models. The proposed filter applying multiple cascaded modified radial stubs resonators provides a sharp cut off frequency response that has a 185 dB/GHz roll off rate. Also, U-shaped attenuators provide a wide stop-band about 14fc with more than -20 dB rejection. The filter has an insertion loss less than 0.027 dB from dc to 1.31 GHz. The proposed filter has a high figure of merit, equal to 32317. The experimental results are in fair agreement with the simulated results.}, keywords = {Low-pass filter,microstrip,Radial stub,Sharp roll,Wide stop-band}, url = {https://jce.shahed.ac.ir/article_447.html}, eprint = {https://jce.shahed.ac.ir/article_447_48c2ddfedad39646b6810317cdc8addc.pdf} }
