AWR1843AOP: About feeding position

Hello,

Thank you for reaching out to Texas Instruments. Can you elaborate on your question? Are you requesting for the antenna routing from die to antenna? or are you looking for the polarization on the antenna based on feedlines?

Thanks,

E. Shareef

Hello, 

Thank you for your reply. 

> Are you looking for the polarization on the antenna based on feedlines?

Yes. I would like to know the polarization of the 1843AOP antennas and the impedance of the feeding position on the antennas. 

Please advise. 

Thanks, 

Shoko 

Hello Shoko,

Thank you for clarification. I have confirmed that the feedlines for the AWR1843AOP antennas are fed horizontally from the left side.

Hello, 

Please let me know the exact COORDINATES of feeding position of TX1-3 and RX1-4. 

And please don't delete my reply!

Hello,

From the bottom left corner, the center of RX4 is 5.4, 12.4 mm

And the center of TX3 is 7.4, 2.38 mm

The size of each patch on the AWR1843AoP is .71mm x 1.2mm,

Hope this answer your questions

Hello, 

I have already known the TX3 and TX4 antenna coordinates from following thread as I said. 

e2e.ti.com/.../awr1843aop-antenna-absolute-coordinates-in-relation-to-ball-a1

I want to know the coordinates of the "feeding position" of each antennas, not the coordinates of the center position of antenna.

Could you change the person in charge about this questions? 

Please advise. 

Thanks

Hello, 

Thank you for your response. That's what I wanted to know. 

> can you please tell us more about the reason behind this request? 

As I told you before, I would like to calculate the polarization of antennas and the impedance of the feeding position. 

Thanks and regards, 

Shoko
