Wind velocity profile are required for the study of atmospheric phenomena and weather forecasting. Atmospheric radar is a remote sensing instruments, which can observe the air motion of the troposphere with high degrees of accuracy. Wind Profile Radar (WPR) can provide the three dimensional profile of wind velocities and wind direction of each layer of atmosphere in real time and has become crucial to the world today. In this article, the Vivaldi antenna array is designed and developed for WPR that would operate at center frequency of 1.35 GHz and the VSWR <2 over frequency range from 1.25 to 1.45 GHz and also to design and develop 1:4 equal Split Wilkinson Power divider. The microstrip design is optimized and utilized in a corporate‐feeding network for an antenna array. The return loss, coupling, and isolation between the ports of power divider are evaluated to determine the design. Antenna array and the power divider network are mounted back to back on Aluminum plate. VSWR <2 over the band and isolation between outputs ports of power divider are critical design requirements.
