Abstract


Frequency Modulated Continuous Wave (FMCW) radar uses continuous signal that can change its frequency along the measurement in its detection process. The developed FMCW radar will be combined with Synthetic Aperture Radar (SAR) technology that uses signal processing algorithm to improve the resolution of the output image beyond the limitation of physical antenna and will be mounted on the Unmanned Aerial Vehicle (UAV). On this paper, the performance of Vivaldi, rectangular, bow-tie, and quasi-Yagi antenna will be analyzed to determine which antenna is best used in the developed system. The developed FMCW-SAR radar has an operating frequency of 2.4 GHz (S-Band) and requires an operating bandwidth of 80 MHz to send and receive the continuous signal. All of the developed antennas are made using FR4 Epoxy material with permittivity of 4.3 and height of 1.6 mm and each of it was able to meet these specifications. For the developed FMCW radar system, rectangular antenna will be chosen to be improved with consideration of the available space for installation of the antenna.
