Design and Analysis of a Compact Wide-Band BPF using Quarter Wave Transmission Lines.

The design of a wide band bandpass filter is described in this article, which is done by using ?/4 transmission lines and is designed at a frequency range of 12GHz. Sigma shaped BPF is simulated by using EM simulation software An-soft HFSSv13 and is a wide band BPF having a band width of 5.8GHz and FBW of 50% as the center frequency. To determine its applicability for wideband applications, the suggested filter is constructed and tested. To guarantee that it is acceptable for satellite communication applications, many characteristics such as reflection co-efficient, transmission coefficient, bandwidth, and group delay are tested and are compared with the measured results.
