Need help on Yagi antenna design

Hi, i am doing a project on yagi antenna and would like to know the formula for calculating azimuth,elevation and array factor as these are needed from what ive read to draw the radiation pattern.

i hav chosen a freq of about 900MHz and i am starting with a 6 element yagi.
I would also like to obtain matlab code for drawing radiation pattern.

You might try looking for either an online calculator ( VHF/UHF Yagi Antenna Design by dxzone.com ), or Google 'yagi antenna design' and take a look at various ham-related software tools that will make your project easier.

Hello,

You could also try using AN-SOF.

thx for trying to help!my problem is that i dnt have equation for azimuth and elevation for yagi. I have seen equation for others but they are for linear and yagi is not linear.

The calculator does not recommend to use a 6 element yagi for such a frequency. I have google for 2 months already and yet i cant see any equation for yagi.
an sof seems to provide trial version will it be enough to simulate the yagi?

Hi,

AN-SOF trial version supports up to 20 segments, so you could simulate a 4 elements Yagi with 5 segments per element.

MMANA-GAL supports 512 wires and 8192 segments. It is free.

Recently, it was released AN-SOF100, which supports up to 100 segments.

you can get the design equations from antenna and waveguides by K.D. PRASAD
