HFSS Antenna Array Simulation

Hi,

I am trying design a basic array that has 2 elements. I want to create Cardioid Pattern, the distance between two antenna is quarter wavelength and phases are 0 and 90 degree. But the result is not correct. Can someone help me to find what i am doing wrong?

Hi ctyz,

I took a look at your file, and the setup looks correct. The behavior you're looking for may simply be slightly outside of the narrow frequency range you're observing -- I would try increasing the frequency range and see what happens. Also, for best results, use a discrete frequency sweep.

Good Luck!

thanks a lot i will try :)
