UWB Multilayer Power Divider with High Isolation

By Long Xiao and Tao Yang
Progress In Electromagnetics Research C, Vol. 50, 57-63, 2014


A novel compact slotline power divider is proposed in this article. This presented power divider employs a novel configuration with one lumped resistor, which makes it surpass most antecedent UWB power dividers based on microstrip-to-slotline transitions in aspect of isolation between output ports and return losses at output ports. The simulated and measured results illustrate the good performances of the novel power divider on return losses at all ports, isolation, amplitude and phase balances between output ports, as well as group delay over the wide frequency band from 3.8 GHz to 10.4 GHz.
