AWR1843BOOST: Distance between transmit and receive antennas

thank you for your reply.

What I want to know now is how far Tx anntenna and Rx anntenna are apart.

When I actually measured it, I felt that it was 1.5 times the distance between Rx anntenna, so I asked the above question.

I'm sorry to ask you a difficult question.

Hello, thank you for answering the question

In fact, how did you decide on the minimum distance you should talk between Rx and Tx?
I was worried that if it was too close, it would have various adverse effects.

There was a typographical error in the previous reply, so please see this reply.

thank you for your reply.

That means that the antenna spacing was set so that it could be placed on the board that was originally decided.

Another question is that only the center of the transmitting antenna is off by half a wavelength. Did this shift to make the length between the transmitter and the transmitting antenna the same?

Or are you thinking of increasing directivity?

Thank you for your reply

I would like to ask why the center of the transmitting antenna is shifted by half a wavelength as shown in the figure.

Thank you for telling me!
