I don't need a long range. 100 meters will be plenty. If so,
Has anyone tried PCB antenna, which is just copper etched onto the PCB? Shape? Width? Length?
How about 1/8 of wave length or 1/16 of wave length?
Because in my environment, it is difficult to keep all antenna perpendicular to each other.
Thank you for your input.
Maybe you could find some answers here: http://colinkarpfinger.com/blog/2010/the-dropouts-guide-to-antenna-design/
That's a great article :)
