I'm looking for a book that describes VHF and UHF antenna designs from a mathematical approach. This is to say that while every other ham book I have read about antenna design may be correct, I want to do the math for myself. It's one thing to know "This antenna has 19dB gain at 444.075 MHz". It is another thing to be able to calculate the gain of an antenna that you haven't built yet. Thanks [in advance] for the pointers, Andy Beals ps. Apologies to Ed Nather@utastro. -- Andrew Scott Beals KC6SSS abeals@autodesk.com Marboro: War Ich Rindveh bin.

It turns out that standard antenna design theory, and the math involved, is not always simple or obvious. If you are looking for "rules of thumb" on certain antenna types (say a Yagi with "n" elements vs. frequency response in certain bands) then there are simplifying equations that you can probably find in any reasonable RF design handbook. If you are actually after real design modeling of antenna or antenna arrays, I would suggest that you visit a good university book store at a campus that offers advanced degrees (or at least good undergrad) training in antenna system design. Pick up their latest text on "Basic Antenna Theory," dust off your notes from Advanced Engineering Math 4xx, and enjoy. > > Thanks [in advance] for the pointers, PS: My antenna design course was over ten years ago at Virginia Tech, and the text was by Dr. Stutzman - he taught the class, and the text was photocopied from the working manuscript for his [then] yet-to-be-published tome "Antenna Design Theory." It was a very complete treatment, 17 chapters, about 300 pages. Don't know if it is still in print. > > Andy Beals > > ps.
