Title: Tri-section wideband branch-line hybrid: Design, simulation technique and measurement
Keywords: Defected ground structure (DGS), Multimethod simulation, Wav

Abstract: In this paper, a possible solution for multimethod modeling of wideband branch-line hybrid is presented. Solution is based on the wave digital approach taking into account directly the scattering parameters of the microstrip lines with defected ground structures. Defected ground structure is used to improve the performances and the frequency responses of the designed wideband hybrid. As an example of application, a tri-section wideband branch-line hybrid for operating at center frequency of 2400 MHz has been design and fabricated. The predicted and measured results show very good agreement.
