Abstract

SAR (Synthetic Aperture Radar) is a remote sensing system using radar for high resolution image capture. The use of different frequency bands on SAR, will result different effect of image. The higher frequency used, the higher resolution of resulting image. The lower frequency used, the higher penetration ability. Therefore, using dual band antenna on the SAR system can improve the data collection and information of the target, also reduce its size. This study designs dual band antennas at 1.27 GHz (L-Band) and 3 GHz (S-Band) frequencies. To obtain the characteristics, the antenna is designed by slotted patch technique and using proximity coupled feeding. As a result, by using dielectric FR4 Epoxy with relative permittivity 4,6, the antenna working at frequency 1.27 GHz with return loss -25.131 dB, VSWR 1.1201, and bandwidth (return loss ? -10 dB) 19.9 MHz. While at 3 GHz work frequency return ross is -16.802 dB, VSWR 1.3381, and bandwidth (return loss ? -10 dB) 125.3 MHz.
