Radiation Pattern Optimization of a 6 element YagiUdaAntennaThis example optimizes a 6 element YagiUda antenna for higherdirectivity at zenith elevation 90 deg The design frequencyand typical dimensions of the metal structures are chosen for VHFoperation The design of a YagiUda is a challenging task owing tothe sensitivity of the pattern to physical parameters This examplewill design a YagiUda antenna by using a direct search basedoptimization approach The YagiUda antenna is a widely usedradiating structure for a variety of applications in commercial andmilitary sectors Arguably the most popular use of this antennawas in reception of TV signals in the VHFUHF range offrequenciesThe Yagi is a directional travelingwave antenna with asingle driven element usually a folded dipole or a standarddipole which is surrounded by several passive dipoles The passiveelements form the reflector and director with the name identifyingthe position relative to the driven element The reflector dipoleis positioned behind the driven element in the direction of theback lobe of the antenna radiation while the director as the namesuggests is placed in front of the driven element in thedirection where a main beam would formThis example requires the following productGlobal Optimization ToolboxDesign ParametersWe begin the process of designing the YagiUda antenna usingoptimization techniques Choose the design frequency at the centerof the VHF band 2freq 165e6wirediameter 19e3c physconstlightspeedlambda cfreqCreate See Answer
