printed yagi array in HFSS - 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: printed yagi array in HFSS
Posted: Mon Dec 05, 2005 4:52 pm 
Hi,

I am trying to simulate a printed Yagi array (i.e., multiple Yagi antennas on a common substrate) using HFSS v9.2. I want to study the mutual coupling effects and the radiation pattern. I am not sure I can use the array synthesis tool because, in my structure, the Yagis are not oriented in the same direction. I tried specifying 1 port for each Yagi and thought of looking for the S21 parameter. But I get a value of -280dB, irrespective of the spacing (even when 2 Yagis overlap!!). Also, when I look at the radiation pattern, I get the pattern of a single antenna only, even when there are 2 Yagi's. The pattern that I obtain is that of the antenna for which I defined Port 1. The pattern of the other antenna (with port 2) doesnt seem to be calculated!!

Can any one help me with this??
