Abstract. The two asymptotic formulas for a biconical antenna radiation pattern have been obtained. One of the formulas is valid near the axis, the other - away from the axis of the antenna. The calculation results with using these formulas for biconical antenna radiation pattern are compared with the corresponding results obtained by the method of integral equations. It is shown that the developed asymptotic theory allows to calculate the radiation pattern practically in the entire range of observation angles.

Keywords: wave-short asymptotics, ultrawideband antennas, biconical antennas.
