* is there an EVM variant with separate antenna module, or could the EVM be modified to have a separate antenna module?

* under which angle is it possible to still get reliable heart-beat values with our vital sign demo? Would it be possible to position the radar between two persons with a distance of 0.5m from each, and still get reliable data from both?

    Dirk,

    At this point, TI has released only one antenna variant for the AWR1443BOOST. The same antenna pattern is also seen in the AWR1243BOOST EVM. The AWR1642 has two antenna variants, one for the AWR1642BOOST and another for the AWR1642BOOST-ODS. The AWR1642BOOST-ODS has an antenna pattern that provides a wider field of view (FOV) in both azimuth and elevation to mimic a 4x3 antenna configuration.

    The antenna patterns that are provided in our EVMs online can be leveraged as a starting point since we provide the design files online for these EVMs. Any additional antenna development will be the responsibility of the customer.

    With regards to your second question, it is not possible to use a second radar sensor and capture data on two people as the antenna radiates out in one direction and not out in both directions. So this setup would not be possible. With regards to the position of the sensor, please refer to the documentation of the Vital Signs Demo which can be found on TI's Resource Explorer at dev.ti.com for the proper placement of the sensor.

    Regards,
    Kyle
