[RC232] Can you please confirm the width of the PCB trace from the RF pin of the RC1140-RC232 to the copper pad we use to connect a wire antenna in order to achieve 50 ohms Z0? We’ve also done the layout so the power plane has a cutout below the microstrip.

There are several microstrip calculators online and they have always given correct results for me.

What happens in the power plane is not important to the microstrip.
