IWRL6432: I'd like to ask to you about antenna design

Hi,

With this antenna layout, you may not be able to estimate the incoming angle of arrival if it is greater than about 25 degrees in the azimuth because the upper right antenna is more than half a wavelength away from any other antennas. With the original antenna, you will not have this problem. With the proposed antenna too you will need to modify the processing chain to account for the antenna positions.

Best,

Nate

Hello

Thank you for your kind explanation. I have another question because I don't understand one thing

1. You said that 'in the azimuth because the upper right antenna is more than half a wavelength away from any other antennas. '

 the upper right antenna means the antenna I circled in the picture below?

2. I think the antenna where azimuth and elevation are calculated looks like the picture below

Thanks

Thank you so much!

Hi Nathan,

Sorry to enter your convo, but i am curious, if I it is possible to use the half wavelength array for normal AoA, and use one and half wavelength array (as in this picture) as kind of "zoom in"  AoA, that has small FoV, but higher resolution?

Thank you very much.

Regards,

Wolfgang

Hi Nathan,

I am sorry, that I don't make my intention clear enough. My question is, is it possible to use more than 1 array for the same axis (for this example,the azimuth, with one array is 4 elements, while other is only two elements ) in iwrl6432? 

Thank you very much,

Sincerely,

Wolfgang

Ok, it's clear now.

Thank you.

Regards,

Wolfgang
