Good news to everyone..
It has come to my attention that CST, the best electromagnetic simulation package today (IMHO), has started offering a free student edition since May, 2015. You can check the following page for the details. https://www.cst.com/academia/student-edition. It is indeed a...

It is well maintained and works pretty well even with Windows 10 x64. I am using it nowadays. It is integrated with a nice geometry builder to enable creating simple geometries with simple clicks. It also talks to a High Frequency (HF)...
There is another free open-source electromagnetic field solver out there! A German product called openEMS , which uses the FDTD method. Matlab or Octave are used as an easy and flexible scripting interface. The outcomes look nice, but no idea about how tedious/simple the setup may be. Here is...
Dear all,
I am planning to simulate, and in a single setup, an FSS-Antenna system. I need to study the effect of different field patterns of a source antenna on the performance of an FSS structure. The simulation scenario has the following givens:
1- An antenna, in both the...
I have found a new good free antenna tool, called QAntenna. It is dedicated to viewing and analyzing antennas and their radiation patterns. It provides the user with a 3D view of the models, capable of zooming, and rotating. You can find it here: http://qantenna.sourceforge.net/

Thank you volker,
I also tried Sonnet which seemed to be very good, but the problem is that the limitation is so severe that you can't simulate most of the cases you want.
The memory limitation is only 16 MB which means that you're only able to simulate extremely simple structures successfully...
Nice contribution, we can count on it. They've just released their version 1.0, but it is still not free for I've already registered there as a student and they gave me a license till the end of year 2010, which is about 6 months period. Meaning that they're still not free but good enough for...
Hi guys,
I want you to help mentioning whatever FREE electromagnetic simulation software you know. We want to step up to the free world even in our field, and it's really unfair that humans are far from reaching these technologies just because others want to make money and they don't have these...
The discrete port is NOT accurate in all cases. The results gotten by the waveguide port are more realistic especially for planar structures having a significant width and a ground. That's the reason why they have a "waveguide port" choice, otherwise it will be useless!! So he elektr0 should be...
Well elektr0 for your second question..
I've been working on planar antennas both in Microstrip and co-planar technologies for somehow a long time. I'm pretty sure of what I'm going to tell you now..
YOU ALWAYS HAVE TO LOOK AT THE LINE IMPEDANCE to make sure that your port's size is...
Hey, you didn't show anything about the antenna!
No antenna shape.. nothing except the results..
Anyhow, I said this because the radiation pattern is quite like a monopole one!
So i wanted to see your design and how did it lead to such a pattern..?
Also, It depends on your application you're...
