the current in the object is at least part of the story. if the object is
close enough to the antenna it can also change the currents in the antenna
itself and distort the pattern.

i m studying the distortion of the antenna pattern located near any
conductor. i want to know how do i interpret the patterns obtained. i
know the ideal pattern of the antenna but when i place them near any
conductor, can the pattern distortion be studied by knowing the surface
currents in the object due to the antenna? how the E field and H field
behaviour changes as it travels from free space to any finite conductor
plate?
i m very new to antennas so i need answer in detail to understand.
thanks
