My axial ratio plot shows that my antenna is linearly polarized. But i am not able to conclude that my antenna is horizontal or vertical polarized.How to check this in HFSS?. pls reply me ASAP
Please show the far-field patterns at phi = 0, 45, 90 and 135 deg planes. After seeing that, we can make some suitable comments.
or simply put a sole point at the farthest distance, and apply there "plot vector field"; then see the animation.
I have attached the radiation pattern and Theta vs Gain plot for phi=0, 45, 90, 135, 180. Sudipta Maity
Thanks for your reply. Plz, provide the plot of (a) E_theta and (b) E_phi or (a) gain_theta and (b) gain_phi. Predicting results from Er_total may not be accurate/authentic.
Best wishes.
no, really, if you just want a direction, putting a non-model point in main direction at the edge of near-field zone will show you all you need without guessing. just apply there vector E-field plotting and see. The ellipse can be oblique, so judging by patterns only will not give you an immediate answer.
Try to plot Gain_X and Gain_Y w.r.t. frequency in HFSS and conclude which one in higher than other X or Y. The higher gain will show plane (XZ or YZ) of polarization.
best wishes.
Thank you all for your valuable answers.I will try all the methods. I have attached the E theta and E phi plots Sudipta Maity
From the attached plot it is clear that gainx has the highest value. so, can I conclude that my antenna is horizontally polarized
Hi, one way for determining the polarization direction of the antenna is to put a non-model plane at a distance of antenna and plot E-FIELD on the plane. Then animate E-field. By this technique the polarization can be specified.
