Abstract
This article shows that use of artificial dielectric in form of two-dimensional array consisted of small plates can transform electrical input impedance of printed biconical vibrator in ultra-wide bandwidth and improve quality of its matching. It is also found that use of this artificial dielectric eliminates deep dip in radiation pattern of planar biconical vibrator in direction normal of its plane at high frequencys.
