Default Antenna Pattern Shaping

I have a 1086-1094MHz monopole (rubber-ducky) antenna mounted
(vertically/BNC connector thru circular ground-plane).

I would like to modify the ground plane so that it sees only signals
in a cone from 45° above horizon and upwards.

I'm clueless in this antenna world.

How should I do this?

Thanks!
