Abstract

Microwave band pass filters are one of the vital components of wireless communication systems. Microwave communication systems, expanding radio frequency (RF) filters operating in the microwave frequency range are needed for applications including wireless and satellite communications as well as military applications. Most communication system contains an RF front end which performs signal processing with RF filters. Planar or printed circuit board (PCB) based filters are popular and relatively practical to design. Band pass filters are important components of wireless communication networks. Signals that are sent and received must be filtered at a certain centre frequency and bandwidth. This paper describes the design of low-cost C-band parallel coupled microstrip band pass filter (BPF) by using microstrip layout at center frequency 5.8 GHz for permittivity 4.4 value with a substrate thickness 1.6 mm for order n = 3.
