A cigar antenna fed by a metallic waveguide is analyzed using the body-of-revolution FDTD method. The effective relative permittivity of the cigar structure is numerically evaluated. The properties of the cigar antenna agree with those of a dielectric rod antenna whose effective permittivity is regarded as being the same.
