I ran two simulations for a 3-element dipole array.
In the first simulation, the source excitation integration line for all the 3-elements was pointing in the same direction and I was getting
Pincident = 3.0 W
Paccepted = 2.5 W
I changed the direction of integration line of the middle dipole and the results became:
Pincident = 3.0 W
Paccepted = 2.95 W
So, when I alternated the direction of integration lines, Paccepted value improved denoting less impedance mismatch. How is that possible? Why alternating the direction of the source excitation integration line affects the power measurements in HFSS?
I was wondering about how to reduce impedance mismatch between dipole array elements in HFSS. If someone can shed more light on this topic, I'd appreciate it.
Thanks.
