Hi, Gurus,

In TIDA-020047 design, the antenna wavelength are different.

As tiduf12 Figure4-2, the antenna is designed with wavelength 3.918mm.

But In TIDA-020047 design, RX antenna in D1 or D2 are placed with half wavelength 1.9mm. i.e. wavelength 3.8mm.

So, why Why the antenna wavelength are different? Any pro from this design?

Wavelength used in the design is 3.918mm. I'm checking the distance between d1 and d2.

Yes, but the RX1 and the RX2 of D1 are 1.9mm placed, which means 3.8mm.

Why such design?

Yes. That is what I'm checking.

Hi, Shareef,

What's going on? Could we change the spacing when producing the PCB board?

Hello,

Yes, you can have a RX-RX spacing of 1.959mm.
