please help me about this helical antenna model

helical antenna.rarhello everyone ,i need some help . i have a helical antenna model in hfss ,plz help me check the mode right or not ,and can you simulate it and give me some advise about helical antenna simulation.

Contact your local Application Engineer and request the Antenna Design Toolkit. This Toolkit will automatically create helical antennas (and quadrifiliar) for both normal and axial mode operation. It gives a great starting point and it completely creates the HFSS project including the solution setup and frequency sweep. It is an unlicensed feature, so you just have to request it from ANSYS.

Have Fun :)
