A Novel Design of Wideband Gysel Power Divider

In this paper, a novel design method of wideband Gysel power divider (GPD) is presented. The detailed design procedure of this mothed can expand the bandwidth by solving specific equations of frequency
$f_{m}$
. For verification, a GPD operating at 2 GHz has been designed, fabricated and measured. The measured results exhibit the novel low-insertion-Ioss GPD has 15 dB input and output return loss bandwidth 50%, and the isolation bandwidth 65%, which agreement with simulated results well and indicate the validity of the proposed strategies.
