IWR1843: Recommended material for radomes

c64

Part Number: IWR1843

Hi,

I was wondering if there are any documents describing the recommended materials to use as a radome for the mmWave sensors. I know that teflon-based radomes are recommended, but are there any particular ones? Also, what about PEEK material?

Thanks!

Hello,

You could refer to below app-note section 5. Yes, PEEK material is also considered for the Radome material. PTFE materials are most preferred due to their low deictic constant (fairly constant across frequency) and low dissipation factor (Low loss material).
