Polarization and position mismatch loss

[thranduil]

Hi all guys,

I would like to ask you about position of two dipole antennas and the possible losses.
In short, what happens when two dipoles are parallel but they are not on the axis of max gain? For example, what happens when receiving dipole is parallel to transmitting dipole but is on certain height? Is there any losses due to the fact that wave comes first on the lower side of the receiving dipole and after that to the upper side.

Best and thanx

Provided you are in the far field range, the signal loss can be easily caculated by looking at the dipole's radiation pattern.

Should receiving dipole in a far field be "tangent" to the radiation pattern of the transmitting antenna in order to receive max. power?

Maximum antenna gain is achieved in the plane perpendicular to the dipole rods.

Hello again,

what happens if two dipoles parallel but not on the same height?
The best case is if the line that connects middle points of those dipoles are perpendicular to both of them.
But what happens if they are not on the same height, which means they are parallel but the line that connects their middle points is not perpendicular to them?

Thanx
