Wind profiling radars operating in Doppler beam swinging mode needs to have large antenna array in order to have a narrow beam for wind direction accuracy. To meet the above requirement, in the present work an array with 8 elements configured in an 8X1 is designed. The antenna inserted is a co-axial probe (Probe feed) to the patch near its resonance in ‘L’ band is carried out. Principal plane 2-dimensional radiation patterns at 1.28GHz have been computed for single element and 8X1 linear array. The results of linearly polarized coaxial probe single element are generated using IE3D software. Using single element as basic building block, an 8X1 linear array was designed. The results obtained are presented succinctly. The inferences from the design of coaxial probe antenna are presented.
