Input impedance of spherical dielectric antenna excited in TM symmetric mode

A K BHATTACHARYYA

Abstract


An experimental study of the input impedance of spherical dielectric antenna excited in TM symmetric mode in the X-band has been presented. The spherical antenna has been excited by a coaxial conical feed filled with the same material as the antenna. The experimental input lmpedance of the sphere has been obtained by finding the impedance transforming property of the conical feed.

Keywords


Input impedance; spherical dielectric antenna; TM symmetric mode; conical feed.
