| Summary: | The growth in the number of vehicles, especially four-wheeled vehicles in
Indonesia, is getting faster every year, especially with the many credit schemes that
make it easier for consumers to own their dream vehicles. But unfortunately, the
vehicle safety regulations in Indonesia are not strict enough so that many of the
four-wheeled vehicles marketed in our country are far behind vehicles marketed in
other countries, especially in terms of ADAS technology. This research aims to
develop one of the many forms of ADAS, namely FMCW-based object detection
sensors that work at a frequency of 6 GHz which is still very rare to find in four-
wheeled vehicles marketed in Indonesia. The research will be divided into two
subsystems, namely the transceiver subsystem and the antenna subsystem where in
the transceiver subsystem will be developed SDR and PCB circuits that can
integrate IC components that make up FMCW radar, while in the antenna
subsystem will be developed a patch microstrip antenna that can work at a
frequency of 6 GHz. The SDR design will be made using LabVIEW software by
referring to a simple FMCW radar diagram block while the PCB circuit design will
be created using Eagle software with datasheet references for each builder
component while antenna design will be developed using an antenna design
software. Through this study, it was found that the limited number of high-
frequency transceivers in Indonesia, especially for automotive applications, is
caused by the complexity of the fabrication process, the limited availability of
components that can work at high frequencies, and the limitation of testing tools for
high-frequency radars. Locally fabricated PCBs have a fairly large path loss, around
-32 dBm, adding to the need for a powerful power amplifier to be able to transmit
signals over long distances, while some patch microstrip antenna designs with a
working frequency of 6 GHz have been successfully made in a relatively small size. |
