CCS/AWR1843BOOST: The Receive Antenna gain of AWR1843BOOST

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1243, AWR1243BOOST

Tool/software: Code Composer Studio

Hi,

    Using mmWave Sensing Estimator, by increasing  transmit  and receive antenne gain,the max range for typical detectable object can be increased.In the user's guide, it descripts as follows:

Transmit Antenna Gain - Gain of the transmit antenna design. 8dB for TI mmWave sensor EVMs.

Receive Antenna Gain - Gain of the receive antenna design. 8dB for TI mmWave sensor EVMs.

I want to know the gain value for the AWR1843BOOST EVM.If I want to change the value,what should I do.Except that, I want to know the receive and transmit antenna gain of AWR1243 EVM.

Thank you,

Regards,

Rata

    Hello Rata,

    You can refer to the AWR1843BOOST and AWR1243BOOST user guides for the antenna gain details. If you want to change the antenna gain you will have to build your own PCB with a different antenna of the gain value you wish to have.

    regards,

    Hi Vivek,

         In the user guide, I can find the content as follows:

    As the figure describes, the max receive antenna gain is 10.5dB,is that right?

    Regards,

    Rata

    Hello rata,

    That is right. As shown in the plot the gain will reduce with larger angle.

    Hi Vivek,

         Thanks,I got it.I have another question,using the mmWaveSensingEstimator,my configuration parameters is shown in the belows:

    From the configuration, we can see that the max range is 85.78m for the car.Whether it means that the range is limited in the scope [0m,85.78m],if we want to extend the scope,  we will have to build our own PCB according to our needs.But we are unprofessional for the antenna design,can you provide the design solutions for the antenna?

    Thanks,

    Regards,

    Rata

    Hello Rata,

    If you want to learn about mmwave antenna design you can refer to some of the online material like this tutorial: https://www.keysight.com/upload/cmc_upload/All/2Feb17Webcast.pdf

    Before you go into new antenna design I would suggest look into working out  the chirp parameters itself to see if you can achieve the range you are looking for. Please refer to the following app note to learn the basics of the computing the system parameters from the chirp parameters:
