polarization determination

[danesh]

hw to determine the polaziraion of our antenna before design?

Hi,

I am not sure I understand your question. but tne factors that determine the polarization of the antenna ar

1. The antenna shape, e.g. helical antenna has elliptical polarization while pyramidal horn has linear polarization.
2. The antenna feed.

hello adel_48

for ur kind info. helical antennas use circular polarization

 

[adel_48]

Hi,

For certain dimensions only helical antennas produce circular polarization. If I remember correctly this occurs when the dipole moment of the magnetic dipoles equals that of the electric dipoles.

Best regads,

The antenna lying or standing also affects its polarization, vertical or horizontal polarization.

Hi all,
Can anyone tell me the polarization of full wave loop antenna?
