This paper presents development of circular polarization 5.5 GHz microstrip antenna E-shaped for synthetic aperture radar Communication. Microstrip antenna designed Truncated E-shaped the centered frequency is 5.5 GHz and bandwidth that is wide 200 Mhz for Synthetic Aperture Radar communication. The proposed antenna on 1.6 mm thickness of FR-4 substrate with the dielectric constant 4.6. The best simulated result can achieve -10dB reflection coefficient bandwidth 600 Mhz, VSWR 1,578, gain 5,67 dbiC and axial ratio 2,947 with left-handed circular polarization. The best measurement result can achieve -10 dB reflection coefficient bandwidth 951 MHz (5.304-6.255), VSWR 1,25, gain 6,17 dBiC with left-handed circular polarization.
