Site Links - Antenna Topics
Theory of AntennasThat's the heading above the lists of links and downloads on this homepage. But we're dealing with tutorials on the basic principles here, the list is never ending, and it's impossible to itemise everything there is here on this subject. So just have fun rummaging around!
Marska WLAN Pages
Even up in Finland there are some active people, which is why it’s worth rummaging around on this homepage. One very interesting subject is what you can find here under the heading “2.4 GHz WLAN antenna – Do it yourself”. You can choose between English or Finnish texts. But anyone who doesn’t speak any Finnish will have given up already during the search, and will not be looking for it any longer.
Microwave Active Antenna Group
This site (which is run by the University of Colorado) is also guaranteed not to be boring, for the students are very active and post their well documented research results on the homepage.
We know that antenna developers come up with numerous “infinitely variable concepts”, which they never stop playing around with and changing – there’s no end to it. This often leads to solutions that we would never have dreamed of. The “Vivaldi antenna” falls into this category. Just take a look at how something like this makes out in a radio telescope. And if this is your kind of thing, a search engine can provide plenty of additional links on the subject.
This page offers a total of 115 links for you to click on, and each one leads to a program or a set of programs for antenna calculation. The same homepage also offers any amount of practical examples, and they’re even broken down by type or frequency range.
Would you like a bit more information about the principles of antennas? If so, please just take a look at this page, as information is presented here in an attractive form, and it’s a joy to read. There are also additional links to half the antenna world.
Would you like a few application notes on the subject of microstrips / antennas / couplers? There’s some stuff you can download here, but it’s also worth taking the time just to look.
Collection of antenna design software
Just another little collection of CAD programs for antennas. Things keep turning up here that you didn’t know before.
Cubical Quad Antenna Calculator
If you’re planning a project like this, you need only click on this page and then you can design the whole antenna, right down to the mast.
If you need to refresh your basic knowledge of antennas, or you want to gen up on the problems and concepts associated with modern WLAN antennas, or to look for frequency occupancy tables, or to examine this, that or the other, you can look at problems more closely by visiting the “Technical Reference” section of this homepage

Another antenna topic, but this time a general tutorial. This is not only for the specialists but for revision and to test your own knowledge or for filling the gaps in your knowledge.
Basic Antenna Theory
For those who want to study the basics of antennas at a very scientific level should take a look at this university site.
EZNEC Model files
EZNEC is a simulation program for wire antenna simulation in the frequency range up to 1GHz. It can save many unnecessary prototypes and tests. The program does not give complete building and assembly instruction, but the simulation results are so good that usually only fine adjustments are necessary. EZNEC is a good low cost entry into simulation. To save re-inventing the wheel it is a good idea to look at finished projects. This helps to learn how the software works and secondly and existing project can be adapted. Here is a source of such small project.
Also this site has an interesting offer at the end to download an antenna collection:
Orban - The Basics of Patch Antennas (Updated)

Since we are already looking at antennas, here are some more. Spend some time to browse through all of the information on offer.
The keyword “NEC” is well known for simulation of wire antennas. More precisely: NEC2, because the much improved current version NEC4, cost too much at the moment.
For some years 4nec2 has been at the forefront of design software. Not only because of its beautiful coloured 3D result diagrams and structures, but because it offers almost unbelievable possibilities during design and the optimisation - and it is free! (a friendly amateur made the comparison of the bicycle to the Porsche for the software changes).
Again and again it is interesting to read are such introductions, particularly if they are easy to read and understand. In addition this is a visible pdf file - an interesting read.
