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??

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
