Hi Robert, I keep getting Net antenna warning on DRC.What is it? and how can I resolve it?

Is not that a different DRC? Go to your PCB, go to the right bottom corner and press "PCB" button. Then select "Rules and Violations". Browse through the violations, double click on it, press "JUMP" and "HIGHLIGHT" to identify the exact place of the DRC. Possibly, please attach a screenshot with "Rules and Violations" window + your PCB with DRC.

I would have to see your PCB, but I would expect getting this kind of error when VIA is connected on 1 layer only. Double check if all your polygons have Net Name assigned. I am sure you can figure it out. Please let me know then what the problem was.
BTW: try to check "Remove Dead Copper" when you double click on the GND polygon pour.

Hi,
I got the same Net Antenae violation on Vias. But fortunately I was able to find a solution. Here it goes
Firstly, I added shielding vias surrounding a RF trace. The vias was given GND net. At this time I had the following stackup
1. TOP
2. GND
3. IN1
4. IN2
5.PWR
6. BOT
There was only 1 ground plane dedicated to my PCB. At this time I thought of disregarding the violations thinking that its a bug in Altium.
Secondly, during layout review my colleague told me add GND copper pours in the Inner layers to get Stripline trace and better impedance. Suddenly the NET Antenae via violation went away.
I was because of insufficient GND planes in the PCB, Altium was showing Net Antenae violation (according to my case).
Hope it helps someone.
Cheers ! Bye.
