摘要:Wind profilers depend upon the scattering of electromagnetic energy by minor irregularities in the refractive index of air. The refractive index is a measure of the speed at which electromagnetic wave propagates through a medium. Atmosphere is the medium for wind profiling. 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 4 elements configured in an 2X2 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 430MHz have been computed for single element and 2X2 linear array. The results of linearly polarized coaxial probe single element are generated using IE3D software. Using single element as basic building block, an 2X2 linear array was designed. In this paper Aluminum sheet is used as material for ground plate and patch, air is used as dielectric substrate. IE3D software is used to design and simulation of antenna array. The results obtained are presented succinctly. The inferences from the design of coaxial probe antenna are presented.
