A good source is Ham radio websites - the easiest way to find many is a lookup table of call signs, a call sign is usually sufficient to find if that operator has a website.Simple laws of designing Printed Circuit Board (PCB) for high frequency:
- Use ground (-ve) planes as much as you can,
- Draw 45 degree angle traces instead of sharp 90 degree,
- Make as much as narrow/compact the board
- Better to use double layer board with one layer as a dedicated ground plane
- Better to choose surface mount parts instead of through hole
Another resource that might be worth a look is americanradiohistory.com - there's a big magazine archive there. There's more magazines on the electronics and books site - but sometimes that server takes all day to give just a directory listing.Hello,
As @ian field said, HAM radio will be a good start for RF design.
Perhaps the article in this old 73 Magazine might already give you some ideas:

You can also look on the internet for a lot of PDF's:
