    Hi all,

    I'm wondering if anyone can help me out with some basic RF antenna design.
    Ideally, can someone point me to some freeware antenna design software
    that can calculate information about bowtie dipole antennas?

    I've read some material on design but I'm still not certain about how the
    dimensions of the antenna are determined. The calculations are pretty
    simple for a regular 1/4 wavelength dipole antenna, but I can find almost
    NO information on a bowtie antenna other than basic definitions.

    if there's any freeware antenna design software recommendations, I'd
    really appreciate it. Thanks in advance!
     
  2. I'm sure those knowledgable chaps at r.r.a.a will be able to assist
    you (added herewith).

    If you can find a formula, the software should be a snap to write.

    Have you looked for a formula for bowtie antennas? http://www.google.com
    might be helpful. Maybe

    Good Luck!

    All you have to remember is -

    Wavelength in metres is 300 / Mhz

    For performance of simple antennas, download in a few seconds programs from
    website below and run immediately.

    If you are wanting info on aerial design you should be looking to the
    publications of the RSGB (in Britain) and the ARRL (in the USA).

    They have both published MANY articles on the subject, and certainly the
    RSGB puiblish several whole BOOKS on it.

    You don't say what wavelengths/wavebands you are interested in - the design
    data and constructional techniques vary enormously from one band to another!
    What band are you looking at? LF, HF, VHF, UHF or microwave? They are all
    very different!

    And finally, are you talking about receiving aerials. or transmitting ones?
    There ARE some differences!
