What dimension factors contribute to the resonating frequencies of a spiral antenna?

[budder8818]

What are the primary dimension factors that contribute to the resonating frequencies of a spirial antenna? Like radius of coil or thickness of wire?

Thank you

Re: Spiral Atenna

Material properties, thickness, loading etc are also present.
So best way is to use the simulation tools to find all of the antenna parameters.

Thank you, would you suggest CST Microwave Studio?

Re: Spiral Atenna

yes, CST & HFSS are the tools that you can use.
you need to consider the compression, diameter and the length of the spiral antenna that contribute the resonant frequencies.

You can use IE3D, momentum, EMDS, AMDS too.
