Design of 2-element Ultra Wide Band array antenna for satellite and radar communication

Abstract

A single layer, dual co-axial feed microstrip array antenna is proposed for the above mentioned communication purposes. We achieve array antenna with a low gain and high -3db beam-width for the application for which it is intended. The magnitude for the above application is very high means it will work in the good manner i.e. there will be no inter symbol interference for the application for which it is intended. The maximum resonance is 99.75Ω at 0.81 GHz and average resonance is 84.75Ω. The minimum resonance gets at 3.83 GHz with 1Ω resonance. We achieve the maximum return loss of about -97.25 GHz and minimum return loss of about -27.5 dB with the bandwidth of 10 GHz. Finally we achieve the -3 dB beam-width of about 156.31⁰ with absolute gain of -9.57 dBi.
