Smith Chart Help - 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.

 Post subject: Smith Chart Help

Hi,

I am self studying transmission lines and I have a question on smith chart. Consider the case when you're given reflection coefficient (tau_r), Z_not, and impedence (Z_r). You want to find reflection coefficient at any distance on transmission line, i.e., tau_d, and Z_d. I'm using
Tau(d) = (1 + Z_d)/(1 - Z_d) to find Z(d) but I don't get angle/phase correct this way. I don't understand where I am making a mistake and I would request some help on this.

Thanks,

A.M.
