Abstract

This paper describes the design and Simulation of an 0.43GHz ultra high frequency band microstrip patch antenna single element and 8-element linear array using RT/Duroid 5870 substrate material with an inter-element spacing of 0.711 for limited scan angle coverage. Wind profiling radar operating in Doppler beam swinging mode and spaced antenna drift technique mode needs to have a large aperture antenna array in order to get the narrow pencil beam is required for wind speed and direction accuracy. To meet the above requirements a microstrip patch antenna single element is used to design a 8-element linear antenna array for Tropospheric Wind Profiling Radar Operating at 0.43GHz. The patch antenna is simulated on a microstrip structure using conventional microstrip technology process. Conception details and simulation results are also given for the both single element and 8-element linear antenna array. The designed and simulated results are presented to verify our proposed area. A full wave electromagnetic simulator zeland IE3D V12.02 is used to validate the design approach. The simulated results below present are valid over the 0.43GHz band and the simulated parameters contains the VSWR, Return loss, impedance, gain, directivity, efficiency and elevation gain patterns.
