In this present paper, a micro strip low-pass filter using hexagonal capacitive patch with the upper cut-off frequency equal to 2 GHz is analyzed and designed. The proposed filter shows significant reduction in the effective area on the substrate along with an improved pass-band performance and a wide stop-band. To verify the analysis, the structure has been simulated using two popular software packages: a) IE3D and b) Sonnet Lite both based on the method of moments technique and the performance of the filter is in the good agreement.
