Abstract

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.

Highlights

Technology in microstrip antennas is currently many used because of its size and shape, it is light in weight, easy to integrate into suitable telecommunication devices and easy fabrication [1] – [4]
The following are the results of the 2019 CST Studio Suite simulation in the three designs, which contain the results of return loss, vswr, bandwidth, gain and axial ratio
For the analysis that I got from these three designs, the results from the simulation in the cst studio suite software and measurements in the anechoic chamber there are quite a lot of differences

Summary

Introduction

Technology in microstrip antennas is currently many used because of its size and shape, it is light in weight, easy to integrate into suitable telecommunication devices and easy fabrication [1] – [4]. Synthetic aperture radar system can operate in various conditions and weather [5] – [7]. SAR is used as a sensor for mapping and its use is in uav, airplanes, satellites and others [5][7],[10] – [19]. The material used in this antenna is FR4, because this material is cheap and easy to fabricate [20]. This study uses circular polarization because circular polarization in uncertain weather conditions is better than linear polarization [8]
