For instance if we take a dipole and then rotate the receiving dipole 90 degrees such that it forms a cross against the transmitting dipole, would the signal be retrieved at all? If it were rotated 180 degrees then surely the electromagnetic wave received would be inverted. How does a patch antenna in a mobile phone overcome this? I can't find any text addressing it. I know at least that the preamble of the packet could tell the receiver the orientation and it could adjust accordingly but I'm still not sure how the perpendicularly angled case is handled.
