Abstract :
Results of analysis of a mathematical modelling of a conic spiral antenna (CSA) with a variable denseness of winding are carried out. The nomograms for a choice of optimum geometric parameters of a conic spiral emitter are obtained. The authors have carried out researches of CSA characteristics and have confirmed shappings- a condition of back axial radiations, and also have revealed potential frequency properties of analyzable radiators, singularity of a modification of CSA input impedance of a modification from frequency.
