Abstract: There is an increasing demand for microwave system in modern communication system due to low cost, compact size and high accuracy. In this paper, design and synthesis of the fifth order end-coupler microstrip line band pass filter has been describe by method of moments, where FR4 material is used with dielectric constant 4.4 at 6GHz frequency. The analytic result obtained through IE3D software and thoroughly discussed.
