A low-profile, compact size and light weight wide band BPF prototype is presented for satellite communication applications (Ku-band). The proposed wideband BPF satisfies the International Telecommunication Union's (ITU) region 3 spectrum requirement. Direct broadcast service (DBS) and fixed satellite service (FSS) in transmitting mode, respectively, employ the frequency band 11.41-12.92 GHz. The proposed filter offers an impedance bandwidth of 1.5 GHz and group delay of 0.2 ns. The proposed wideband BPF is fabricated, and various parameters such as return loss, insertion loss, group delay and quality factor are measured. Miniaturization of filter size reveals the filter's suitability to use on smaller platforms with smaller surfaces.
