In this letter the design and simulation of an 0.43GHz P/UHF band microstrip patch antenna as single element, 2, 4, 8 & 16-element linear array using RT/duroid 6002 substrate was proposed. An inter-element spacing of 0.73λ 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 2, 4, 8 & 16-element linear antenna array for Tropospheric Wind Profiling Radar Operating at 0.43GHz. Conception details and simulation results are also given for the both single element & 16-element linear antenna array. The designed and simulated results are presented. 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. © 2015 IEEE.
