Uwb Multilayer Power Divider With High Isolation

Abstract

Abstract-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.

Compact UWB Power Divider, Analysis and Design

“…The power divider presented in [6] was based on signal interference technique where the short ended symmetrical coupled line and transversal transmission line were introduced at both output ports of the divider. A high isolation was achieved between output ports due to the microstrip-to-slotline transitions [7]. Also, for bandwidth enhancement purpose, a short ended stub was combined with an open ended microstrip line in the power divider structure, as stated in [8].…”
