IWRL6432부스트: Inquiry About Using External Antenna for Flexible Obstacle Detection

Part Number: IWRL6432BOOST
Other Parts Discussed in Thread: IWRL6432

Tool/software:

Hello,

I have a few questions.

I am currently developing an obstacle detection system and would like to flexibly move the antenna for measurement.
However, when the antenna is integrated into the board, it is difficult to adjust its position and orientation, which limits measurement flexibility.

I have a few questions regarding this:

  1. Are there products or methods that allow the board and antenna to be separated so that an external antenna can be used?

  2. Is it possible to replace the built-in antenna on the current board with an external antenna for flexible movement?

  3. Aside from designing the chip and antenna separately, are there other ways to use the board and antenna independently?

I would appreciate your kind response.
Thank you.

    Hi there,

    What type of antenna are you going to use?

    We do not have such examples of a separate flexible/movable antenna design. It becomes difficult to control the impedance for a prolonged or flexible transmission line.

    However, the IWRL6432 device supports three receiver and two transmitters, that can be used with any sort of antennae. If you already have such antenna designed, you can use the device separately on your board with the antenna connected to the device BGA balls with proper transmission lines.

    You can also take a look at TIDEP-01033 reference design that includes a compact antenna design with the radar device integrated. This design has a form factor of 16mm x 33mm. With this much small design, it would be easier to move/rotate the complete system as per requirement without degrading the signal strength with lossy transmission. Rather, the digital data could be taken out to a separate system with longer cables if the host is not supposed to move much.

    Thanks,
