I am not quite sure how to start
this thread; I am involved in this little project
to simulate (using a software package called FEKO)
the radiation pattern of a few antenna types under
a variety of realistic conditions.
all I will be creating 3d models on the package
of a few types of antennas.
To get your
curiosity going I will post a few pictures:
Very simplistic model of a 5 element Yagi Antenna
Radiation Patterns at 100MHz (left) and 95MHz (right)
I have used a few dimension formulas I found
online to optimize the antenna for frequencies of
95.5 MHz. Still it seems to operate better at higher
frequencies as you can see.
So at the moment
where I would really appreciate your help is if
you could provide or point me towards a reliable
source of antenna dimensions.
