## HELP ## what is polarization tilt angle

Hello Guys

please i want to know what is the tilt angle of the vertical, horizontal and circular polarization.

my deeply regards

Circular, linear and circular are all subsets of elliptical polarisation.

I can't say I understand this, but I looked in:

IEEE Std 145-1983
(Revision of ANSV IEEE Std 145-1973)
IEEE Standard
Definitions of Terms for Antennas
Published June 1983



tilt angle (of a polarization ellipse)
. When the plane of polarization is viewed from a specified side, the angle measured clockwise from a reference line to the major axis of the ellipse.

NOTES:

(1) For a plane wave the plane of polarization shall be viewed looking in the direction of propagation.
(2) The tilt angle is only defined up to a multiple of Π radians and is usually taken in the range
( -Π/2,Π/2 ) or (0, Π) .

Hi friend
I think u should ask Mr Google. He have lots of answer for your question :)

Hi friends, thanks a lot for your replies, please help me.

my supervisor told me that the tilt angle for circular polarization = 45 degree, i neeeeeed to know tilt angle for vertical and horizontal polarization.

my deeply regards

hi
I don't know why u can't search in google ?
I hope it usefull for u https://docs.google.com/viewer?a=v&q...2kb_xMnaFeceQA

I have not read that paper (don't have time now), but I think that is almost unrelated. It appears to be about tilting of the antenna which happens on a mast. But that is nothing to do with the formal definition of tilt angle, and its connection with elliptical and circular polarisation.
