IWRL6432AOP: radiation pattern

Mahalakshmi Iyadurai1
Intellectual 300 points
Part Number: IWRL6432AOP

Tool/software:

Whether the 0 degree of FOV  is at the centre perpendicular to device top surface.

How we have to mount the device.

thank you

    Hi Mahalakshmi,

    Could you please explain more on the application?

    IWRL6432AOP data sheet (https://www.ti.com/lit/ds/symlink/iwrl6432aop.pdf) section 7.13 Antenna Radiation Patterns depicts the radiation patterns across azimuth and elevation. The results are normalized to boresight and by looking at them we can consider the antenna position based on the application requirement.

    Ideally the boresight (0deg FoV) is considered to be at the center perpendicular to device top surface of the IWRL6432AOP.

    Thanks,

    Swarnendu

    Thank you for the inputs.

    I am working on a proximity sensing application.

    Since the virtual antenna array has different pattern, not square or rectangular size i had a confusion

    about where the 0 degree of FOV or boresight will be on the surface of the device.,

    I understand from your reply that the center of FOV is at the center of top surface of the device.

    How much angular resolution can be considered for IWRL6432AOP if we use 2TX and 3RX antennas.

    whether we can take , angle resolution=2/(2*3) or

    Whether we have to partition the antenna for azimuth and elevation angle resolution

    like azimuth angle resolution=2/Ntx and elevation angle resolution as 2/Nrx,

    Please clarify the angle resolution for this device.

    Thank you.

    Mahalakshmi, 

    Above attached is the virtual antenna array for the IWRL6432AOP. It has 4-elements in the azimuth plane and 2-elements in the elevation plane. Hence, in azimuth plane it would give angle resolution of 2/4 * 180/pi = ~28 degrees, and in elevation it would give 58 degrees.

    You can take a loot at the radar tool box for more details on the virtual antenna array and other details: https://dev.ti.com/tirex/explore/node?node=A__AX3tKOzzaII2km8208OgmA__radar_toolbox__1AslXXD__LATEST 

    Thanks,
