asymmetric radiation pattern

is it possible to have a asymmetric radiation pattern from antenna ....
what would be current distribution for a asymmetric radiation pattern

thanks & regard

What type of asymmetry are you talking about?

asymmertry ... if u observe radiation pattern then u will find that pattern is symmetric along any line .. say theta = 0, 10 , ....90,
pattern may be expanded from -90 to +90 WITH symmertic line at 0 ... i want to know possibility of generating a pattern obtain on cutting the above pattern at its line of symmetric ...
and the curent distribution on antenna required to have such pattern
