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?

No. The basic PCB antenna starts out as being a length of trace along a portion of the board where there is no ground plane on the layers below. If the available simple length is not enough to achieve resonance, several approaches can be used.

  • One is to zig-zag the trace to increase its effective length.
  • Another is to add a small chip inductor in series with the feed to the trace.
  • Still another is to add some capacitive end-loading at the far end of the antenna trace.

Is paste mask layer, both top and bottom layer, necessary for THT components?

I know the paste mask layer is also called the stencil layer. It’s only used for assembly. I want to know if the paste mask layer (both top and bottom layer) is necessary for through hole components. For SMD components I know the paste mask layer is required to solder the components. Is it necessary for through hole components?
