| Summary: | The navigation system is one of the technological advances that affect human work.
Apart from being used by humans to find directions, navigation systems are
commonly installed in moving vehicles. One of the uses of navigation technology is
for industrial purposes. Industrial navigation systems are used in unmanned mobile
vehicles or automatic robotic machines. This machine is commonly used in storage
warehouses to find out the position of goods, even some robots are designed to help
transport goods. Indoor navigation systems can be made by using an antenna array
to perform sweeping, then the information of power and angle obtained by the
antenna is processed by the position estimation system. The antenna output power
will be amplified and then enter the power divider. The power divider divides the
input power into two, one output to the power detector and the other output to the
WiFi adapter. Because the amount of power that the power detector and WiFi
adapter can receive is different, the output power at the two power splitter ports is
not the same. This final project report discusses the development of a Wilkinson
power divider with unequal output on a DoA estimation tool for indoor navigation
systems. The power divider is designed on a 2.4 GHz Wireless Local Area Network
(WLAN) for the IEEE 802.11b/g protocol standard. The eproxy FR4 substrate was
used as a dielectric with a substrate thickness of 1.6 mm. The power divider consists
of a microstrip type transmission line made of copper with a thickness of 0.035 mm.
Full ground is applied to the design. The SMD 1206 resistor with a resistance of
110 ? is used in the design. In this final project, an unequal output Wilkinson power
divider with a center frequency of 2.4 GHz was successfully developed with an
output power ratio of 1:2,2.
