hello guys
am currently working on R&D with rfid and the esp module.
i am trying to create a wireless transmission of signal from the antenna to the receiver in the sense that i want to use the esp module as a transceiver which means it is going to be connected to the antenna for reading the rfid tages after that then send the tag id to a server or any remote base network.
right now i have a DIY yagi antenna which reads the tags when connected to a tag reader, i want to use the esp as the tag reader instead so i can eliminate the use of wires and buying multiple readers at the same time.
I haven't found anything on this so far so i hope if there's anyone who can help with any sort of idea is welcome.
thanks.

Let me see if I understand what you are wanting to do.
You want your esp to generate a pulse of RF to power the rfid tag and then turn itself into a receiver to receive the data from the rfid tag. Is this pretty much the correct description?
If all wrong, can you show us a block diagram of what you are doing?
yes, turns out i was look at it the wrong way with my first post,
will also like to know if the range of reading the tag is dependent on the reader or the antenna and if 15 to 20 meters range is possible.

That all depends on the amount of RF energy you can deliver to the tag and if your receiver can hear the resulting transmission from the tag. This is not available with any commercial equipment because of international laws limiting the power. But you can create whatever you want for testing, depending on what country you are in.
By the way, what frequency tags are you designing this project for?

I believe the OP is just looking for advice about a regular RFID reader that he can use with his ESP8266. I think the Original Post was just worded in a very confusing way.
