Design and Development of Dipole Antenna for NOAA Satellite Image Acquisition System and Processing

Abstract

Abstract The National Oceanic Atmospheric and Administration (NOAA) satellite is the 3rd Series of American meteorological for take information about the physical state of ocean and atmosphere. This research will describes the design of Satellite Image Acquisition System using two kinds of antenna, double cross dipole and Double V Double Dipole antenna as receiver of NOAA satellite and about performance of receiver system. The designed antenna works at frequency 137 Mhz with omnidirectional radiation pattern. The analysis process with analyzing the data receiving process with return loss parameter, signal to noise ratio (SNR), noise floor and image. The process of receiving data is by connecting antenna with RTL-SDR, SDRSharp software, WxtoImg, and Gpredict that has installed on laptop. Both antenna can receive data from NOAA satellite well, the data received are return loss value, noise floor, and image of Indonesian island that can be used for remote sensing. The antenna parameter for Double V Double Dipole are return loss -30.421 dB, VSWR 1.063, input impedance 51.642 Ohm and Gain 5.2 dB. For double cross dipole are return loss -29.315 dB, VSWR 1.071, input impedance 46.946 Ohm and Gain 4.47 dB. Both antenna have omnidirectional radiation pattern.
