Abstract

In this paper, three designs of Wilkinson Power Divider (WPD) at 9.0 GHz
center frequency are proposed. The first design is 2-way in-phase equal power
outputs implemented on the Roger RT-duroid 6006, PTFE ceramic, relative
permittivity = 10.2 r e and thickness of substrate material h = 0.365mm. The
second design is 4-way and the third design is 8-way in-phase equal power dividers
are implemented on the same substrate. The third design is a new shape of 8-way
WPD consists of feeder connected with four WPD via cut cortex rhombus to
achieve matching with inputs. All designs are simulated by using CAD
(Microwave Office 2000). The simulation results demonstrate that the power
divider works well at assigned operating frequency with compact size. Low
insertion and high isolation are achieved.
