High Frequency Compact Microstrip Low Pass Filter

Merjem Skula, Ismeta Gafić, S. Taha Imeci


The purpose of this work is to discuss the design and analysis of a low pass filter. The research of a low pass filter with a cut-off frequency of 11.45GHz and an area of 13x6.3mm2 is proposed in this paper. Initially, low pass prototype filter was designed with ground layer. The proposed low pass filter is miniature and low cost because it is mounted on FR4 substrate. The FR4 substrate has thickness of 1.55mm. By using three main stubs that are placed symmetrically around X and Y axis is obtained. The cutoff frequency could be changed by tuning filter’s dimensions. The simulations with this design are simulated using Sonnet software and simulation results are reported.
