Help me design a 433 MHz PCB antenna

Hello!
RF is not really my field od expertise, but I hoped to face not that many problems.

I am designing a 433MHz short range radio link, and I would like to employ an integrated PCB antenna.

I found a few general application notes on the net, but still i don not know how to determine dimensions for a given antenna gain and pattern. I haven't seen it anywhere. Yes, I know these are just rough estimates, but I still need some guidance, a place to start and a direction to change things if something go bad.

I would like to specificallu employ a structure I saw being called a loop antenna, where all the components are in the middle of the PCB, antenna making a rim around it. But, no calculations I found...

Could somebody point me to a suitable handbook or design guide?
I checked most of the related posts on the forum. Either I missed something or there is not what I really need

Many helps in advance

I have just seen that I in a way missed the forum. Is it possible for an administrator to move the topis to appropriate, antenna, forum? Without a shitlisting, I hope

Thanx IanP. Very nice
I am afraid I'd be back soon with some other questions
