Abstract:
A novel ultra-wideband four-way in-phase multilayer power divider based on the microstrip-to-slotline transition is proposed in this paper as a complemental slotline power divider with high isolation. Due to the introduction of three lumped isolation resistors, the isolations between output ports in the new structure have been improved. The design expressions have been derived by making use of odd-mode and even-mode method. Both simulated and measured results have proved that the proposed power divider has good impedance matching at all ports, high isolations between output ports, excellent amplitude and phase balance, as well as flat group delay over the wide frequency range from 3.8 GHz to 11 GHz.
