The influence of the dielectric material on the input impedance of covered/loaded biconical antennas is analytically investigated. Novel and accurate analytical expressions for the input impedance of the covered/loaded bicon are proposed based on the mode matching technique. The boundary conditions are also enforced to obtain several simultaneous equations for the discrete modal coefficients inside the radiating region. Study of the input impedance of the whole multilayered structure is accomplished by the cascade connection of mediums as characterized by their constitutive parameters. New and accurate analytical formulas for the covered/loaded biconical antennas are derived and successfully validated through a proper comparison with the results obtained with the commercial software CST Microwave Studio.
