Your screenshot does not give enough information. A guess is that you are trying to build a PCB directly in the PCB Editor without having first made a schematic. In which case the problem is probably that you have not assigned the same netname to both the track and to the antenna. For more help, please clearly identify the antenna symbol and footprint in the library or make your project public and post the link to it here.

Hello andyfierman, Thanks for the information. I am going through it. <br> However, to clarify the question, firstly, I made the schematic and then moved onto the PCB layout. Please, see Below screenshot for the symbol and foot print used in the library.  Below is the connection made in the circuit and I verified that, the net name matches while assembling the component. Please, let me know, if I am missing something here. Once again, appreciate your help. 

@adudekul, Try this: 

Yes Andifierman, it works. Thank you very much. Do I have to make Schematic for this component in the library? I am trying to do this but, if you already have schematic, please let me know. I can add it to the library. Appreciate your patience.

@adudekul, In your schematic, select the Footprint attribute in the antenna symbol then use the Footprint Manager to assign my footprint to it. See Footprint  Manager in the Tutorial.

Thank you very much Andyfierman. I am able to add footprint to the schematic symbol. Appreciate it.
