How to send data using Antenna with PJF-F7992?

Hi everyone,
We have used PJF7992 IC to start the immobilizer. We have used a coil for its antenna. The circuit works properly. Our communication protocol is through LIN. I am going to see the performance of PJF7992 IC first with the help of LIN analyzer.
I see the data I send and receive through the LIN analyzer software on Windows. I also connected the oscilloscope probe to the antenna coil. I want to send a data from the antenna so that I can see the changes in the performance of the antenna with an oscilloscope.
For example I sent the following frame.

55 CF 61 40 8E

By sending this frame, a sine wave was created on the antenna. After a few seconds, this wave disappeared and the voltage stabilized. Also, before the signal on the coil becomes zero, the signal can be zeroed by sending the following frame.

55 CF 61 00 CE

If the explanation is not complete, ask me a question to explain more.
Thank you in advance for your help.

Do you have a designed schematic diagram for this.

I am also trying this with NCF29A1MHN, I have no idea about designing the antenna
