i am doing and project using pyramidal horn antenna as transmitter.
i am having problem in feeding
could please any one guide me about probe feeding and how to measure its distance in wave guide etc.


all details about probe feeding of it.

thanks in advance

Hey Osha,

I just had the same doubt and I did some research in Balanis and papers around the internet, what I found out was:

the distance in the waveguide will be L=λg/4 in which:

λg = wavelength of the wave along the transmission line.

I found out that :



And also, the probe length can be determined by D=λo/4

where λo is the wavelength in free space;


I ran some simulations in HFSS and were very accurately.

If anyone know more about it, please pay attention to them.
