What do you mean when you say "doublet?"  Do you mean a dipole? ANY 
antenna operated on a frequency higher than its resonant frequency will 
have lobes and nulls. In the lobes, the gain may be greater than the 
broadside gain at resonance. This is a simple antenna concept that we 
should have learned by studying any text on antennas, like the ARRL 
Antenna Book.
