Design of U-shaped in-phase power divider employing ground-slotted technique for wideband applications
This article describes the design of U-shaped wideband power divider implemented with ground-slotted technique. The slotlines at ground plane underneath second and third arm promises wider bandwidth performance. In this proposed designed, the second and third arms are formed by microstrip line with...
