**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.
