Would you please offer any tips for high-frequency PCB circuit design?

I wonder if you can kindly give me advises on high-frequency PCB circuit design.
It seems that some aspects need to be paid attention including interference and signal integrity.
Would you like to make me more clear?

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

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.

There will certainly be pictures of RF PCBs, probably some project plans - there may even be tutorials for those willing to do some searching.

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:

Page 28 and on.

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

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.
