What parts of our comments didn't you read?
Do you have a transmitter or receiver somewhere?
Where do you insert the CD in your player, if you don't have a CD/DVD/BD reader? Where do you insert the memory card into an old-time chemical camera?
When you connect an antenna to a TV, you do it because the TV has a radio receiver with an antenna input.
Have you found your development board to have a radio receiver or radio transmitter on it? If you have, then you would know if it also have an integrated antenna, or if it has a connector for an external antenna. If it hasn't a radio receiver or transmitter, then it will not have any connector for any antenna, and you must instead figure out how to connect a receiver, transmitter or transceiver to the board.
All of them, apparently!
"Have you found your development board to have a radio receiver or radio transmitter on it?"
And not just any radio receiver/transmitter - you need one specifically designed (and/or adjusted) to your required frequency (125kHz) and whatever modulation scheme you require and all the other details of whatever it is that you're actually trying to achieve.
