Is it true that PCB antennas can be tuned by only changing their length?

My PCB antennas fail to achieve resonance, though I have changed their length. Our new product project is obstructed due to this problem now. Are there any good solution else?

What are the black spots in lead-free solder joints on PCB?

I am prototyping a PCB, using Chip Quik’s “SMDSWLF.031, a Sn96.5/ Ag3.0/ Cu0.5 solder with 2.2% no-clean flux. I find that the black spots appears frequently in larger pads on my board. I wonder if it is because I left the soldering iron more time heating the solder and that burnt the flux. What is that black residue? Is that a sign of a bad joint or maybe bad soldering technique?

Why does my RF PCB have small holes in the ground polygon?

I ordered RF PCB design and prototype from my supplier . There are something like a hole, but it is not, on the ground surface. What is the purpose of making these holes? The PCB is inside of the E70 433NW14S LoRa module.
