Hi,
I would just need an equation form which I can calculate the aperture efficiency of a circular waveguide antenna. I have data from gain, wavelength and its physical size. The way that is shown in books is:
Effective area (Ae)=(Gain*lambda^2)/(4pi),
Physical dimensions of open end of antenna(Ap)= pi*r^2
Aperture efficiency is Ae/Ap.
The problem is because the result is more than 1, which shouldn't be right. The dimensions of the antenna are smaller than the wavelength. Which formula should I use in this case? I can't find the answer anywhere.
Thank you very much for helping me.
