Designing Microstrip filter is the prime requirement for optimum and efficient performance of next generation communication systems. This research article presents design, and mathematical and numerical analysis of a parallel coupled microstrip band pass filter, its electrical responses obtained through iterative numerical electromagnetic simulations, and discussions on the results measured and tested after fabrication using FR4 substrate. Comparing this filter with international industry standards for its operational frequency applications at 2.4 GHz using Ansoft Designer Software we found satisfactory parameters such as insertion loss above -5.00 dB, reflection loss below -20 dB, negligible energy loss and frequency bandwidth of 6.25%. Volumetric miniaturization and sustainable compatibility we researched are pivotal in RF and microwave communication spectrum resulting into minimum cost to production and a step towards green earth saving the material extraction from the earth’s crust.
