Abstract
The paper discusses some technical issues on the construction of antenna system incorporated with a designed nano satellite. The preliminary LEO satellite model has been developed for the environmental telemetry application. The designed four elements lungs patch structure was initially installed outside the prism body of nano satellite. The lungs antenna array was constructed in such away for electronic rotateable along 90° rotation, vertical or horizontal orientation. Both the numerical and experimental evaluations of 2.4 GHz lungs array confirmed a sufficient operation bandwidth suitable for long distance telemetry application, abruptly, 50 MHz could be achieved. The elliptical polarization property was verified via the numerical computation where the axial ratio was slightly greater than 5 dB.
