IWR6843: TI information for calculating radome material thickness and distance from elements

John Collings

Part Number: IWR6843

Months ago I found a series of formulas to calculate a certain (given DK) thickness and distance from the antenna elements for best loss performance. I can't find this resource anymore. Please direct me to this resource. I am designing an initial 6843 protective cover. Thanks,

Hi John,

Can you please clarify if this is a resource you found on TI's website or somewhere else?

Hi - I thought so, but maybe it was elsewhere. But I thought it was here.

Hello,

You may want to refer to "TI mmWave Radar sensor RF PCB Design, Manufacturing and Validation Guide " application note section 5

Chethan - do you know of any appropriate suppliers of precision thickness PTFE (or others) materials for use as radome covers?

Hello,

It's recommended to use the new posts for newer questions so that other users/customers would be able to find appropriate answers using subject line. I have responded this question on the other thread posted same here for others benefits and closing this thread.

We do not have specific recommendation on Radome suppliers , you could check for enclosures that are Radar wave friendly and there seem to be a variety available when searched online using "Radar Enclosure".

However you could research on this forum some of the customer used below supplier and found satisfactory results.
