Antenna tools

This is really a little treasure chest, in addition to the assembly instructions for a 137kHz receiver and many other things, there is also a special page for antenna freaks with "Antenna tools". These are Java scripts to calculate everything conceivable on line. Would you care for a little taste? "Conversion between Field strength and received power / Field regions / Isotropic losses of free space radiation / field strength, field area and received power…..etc."

Antennex

And finally, another big jar to rummage around in, as here too the concept of antenna engineering is stretched a long way and includes many associated areas.

Address: http://www.antennex

That'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!

Radiometrix

A company which specialises, in particular, on data transmission and modems, including those operating over radio routes. But there are also some neat application notes for the RF freak, quite apart from the many data sheets and other information regarding interfaces.

TX Lines, Antenna Systems, PC Joystick

We don't want to spend all our time talking about antennas, but a homepage with such good tutorials and with so many different applications deserves a mention.

Radio Waves

The site's name gives you a pretty good clue: it deals with developments and products relating to electromagnetic waves. The main theme is antenna development and the production of complete antenna arrays. And because in this kind of work you have to pay very close attention to the customer's wishes, there's also an extensive planning section. One splendidly attractive gift from these people to all RF freaks is the "RW calculator" for calculating and planning every last little thing relating to antennas and receivers, which you can download free of charge. This is really something great, with many different applications of all kinds!

W2BRI's Magnetic Loop Site and PA3CQR magnetic loop antenna page

As always on such sites, the more you nose around and the more stones you turn over, the more treasures you unearth. Very enjoyable and informative to see everything concerning loop antennas summarised here.

Ingecom

Here you can obtain a very well-written article entitled "VHF and UHF Antenna Design". It is really rewarding, either as a stimulus to further research or as a refresher of what you may already know.

Myer's Engineering International

23 years of experience with radio communication systems and antennas... that's what it says in the introduction to this site. Another homepage which can reveal masses of new or fascinating facts for those with an interest in such matters. Seek, and ye shall find...

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.

Vivaldi antennas

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.

Antenna Software

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.

Radiall-Larsen

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

Andrew

This company has specialised in microwave communications systems, and can therefore make comprehensive aids to systems planning available through the Internet without charge.
The “Andrew Microwave System Planner” is very attractive and is also very convenient for use at home (...but you can find even more under the heading “Andrew Power Tools”).

Broadband multi-function antenna suitable for incorporation into vehicles

Something in German for once - though the bad news is that it takes a lot of downloading This modest and unassuming title conceals a Karlsruhe University doctoral thesis 200 pages long, with a good introductory section on the basic principles of antennas.
