Research and design brandpass filter at about 0.9 GHZ on FR4 substrate

Abstract

The purpose of this study was to research and design Band-pass filter (BPF) which makes applications for telecommunication at 0.9 GHZ on FR-4 substrate. The microstrip BPF has several types and designs such as: parallel-coupled, end-coupled, interdigital and hairpin lines. In this thesis, the filter design is to focus on parallel-coupled microstrip line BPF and to approximate the ideal requirements within acceptable tolerance with circuits or systems consisting of real components by simulation with Agilent’s software: Advanced Design System (ADS). Based on this methodology, filters for various applications were designed, optimized, fabricated and measured S-parameters.
