Abstract :

In this paper, a hairpin bandpass filter using coupled lines is designed for satellite applications. Initially, a conventional microstrip parallel coupled line filter is modified as hairpin based folded coupled line filter that works in S-band between 2-4GHz. The proposed filter is designed for the seventh order coupled line and its filter characteristics are analyzed. The idea of folded coupled lines are used for designing the ninth order folded coupled line filter which operates in 2.8GHz and the S-parameter results of filter are also discussed. The proposed seventh and ninth order filter has reduced insertion loss and high performance. © 2018 The Authors. Published by Elsevier B.V.
