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

Post subject: printed yagi array in HFSS
Posted: Mon Dec 05, 2005 4:52 pm
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
Can any one help me with
