Polarization in cellular propagation - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hay all,

Can some one point me to some papers about the best polarization for a base station? I mean what is the average polarization of a signal that came from a cellular phone?

The polarization plane is randomly varying all the time.
many research papers have been written on this topic.

The optimum antenna arrangement seems to be two antennas inclined at 45 degrees to each other and fed through a combiner.

Do a google under "mobile" and "diversity" and "polarisation".

Hi sag
I didn't actually keep any as it is not my present field of involvement.
Did you do a Google Search under "mobile" and "diversity" and "polarisation"?

For me this threw up a lot of references. Many however are subscription-only research institutes I don't have a subscription on. But if you have access to a uni library they would be useful.
