摘要：VHF/UHF Radars use yagi-uda antenna in an array configuration for various applications including phased Doppler radars to probe atmosphere. Wind profiler system is used to find the wind profiles in the layers of the atmosphere. The main aim of this paper is to design a 3-element yagi-uda antenna for wind profiler radar system. The simulations of yagi-uda antenna are carried out using windows based 4NEC2 antenna modeler. The radiation characteristics that are usually of interest in the yagi-uda antenna are forward and backward Gain, Input impedance, bandwidth, beamwidth front to back ratio, VSWR, and magnitude of major lobes and minor lobes of a typical 3-element yagi-uda antenna operating at VHF-Band used in wind profiler radar systems
