AWRL6844EVM: Some question about AWRL6844EVM antenna

Tool/software:

Hi Ti experts,

I'm curious about the antenna design.
I noticed that the trace lengths from the IC to each antenna pattern are all equal, which I assume is to maintain consistent phase.
If I were to design them with unequal lengths or introduce some phase differences, would this cause any issues during measurement?

    Hi Vincent,

    If we are having mismatched antenna lengths, at the RX side incoming varied phase signals can be calibrated, but when the TX signals are phase mismatched there is no way you can calibrate it. Thus, the resulting measurement would be wrong.
