ABSTRACT
ve element linear biconical array is proposed in this paper. The response of the array for standard non uniform amplitude excitations such as Binomial and Dolph-Tschebyscheff distributions are considered. Variation of radiation patterns in horizontal plane, vertical plane, Gain, beam width, side lobe levels and directivity are critically investigated. Behavior of Impedance, scattering parameters of the biconical dipole with frequency in array operation are elucidated. The response of the array and levels of various parameters for binomial and Dolph-Tschebyscheff amplitude excitations are critically compared and contrasted. Plots for various parameters are presented. Simple techniques for controlling side lobe levels and beam width of linear biconical dipole array are introduced.
