IWR6843: advice for antenna design

user5883945

Part Number: IWR6843

Dears,

Do you have some advice for antenna design IWR6843ARQGALP?

The customer's product is space-limited. What are your advice for the layout of the antenna in the vertical direction of 18.3mm to minimize the size.

Hi,

We have tried to contact Ti FAE, but they suggest submitting E2E. Customer use IWR6843AOP to fall detection. Does the white area need to be completely hollowed out?

Hello,

You could refer to below training video's shown below.

For the space constrained applications you could use the small formfactor from the TI EVM.

...

Void or cutout you pointed above helps to overcome small ripples in the antenna radiation patterns. In the some of the short range applications it may not affect the operation, Hence customers need to evaluate this.

Thanks and regards,
