Compact Structure and Low Losses for Wilkinson Power Divider at 9400MHz Frequency for X-Band Antenna System
Abstract: This paper presents
design and implementation 2-way Wilkinson power divider at 9400MHz frequency
which matched to 50Ω transmission line. This design applies Microstrip line
with Roger Duroid5880 Substrate and uses software simulation (ADS 2011) to help
the design. This Wilkinson power divider designed at 9400MHz for use on Antenna
X-Band Radar System. The desire objectives are a power divider can be used in
compact circuit board with low insertion loss and good matching for all ports.
The dimension of the devices after fabrication is 30mm x 40mm. The Voltage
Standing Wave Ratio (VSWR) for all port for both dividers is less than 1.33,
Forward transmission the devices as Divider or the Split power ratio (S21 and
S31)is about -2.522dB, Reverse transmission the devices as Combiner (S12 and
S13) is about -2.861dB. The Isolation between the both output ports shows a
good isolation, less than -11.271dB. The overall result of simulation and
fabrication show a fairly good result.
