Hello. Some of you may remember me, though I don't post much here. Last I posted I was learning to program PIC's. Since then I've done some IR communication stuff with PIC's and some other little projects.
One of the projects I've been thinking of lately would require a very directional radio transmission to be received just a short distance away, < 200 ft (outdoors so IR is impractical and unreliable). I know the basics of how radio transmission/receiving works but I am far from an expert. I'm basically just looking for links, books, or any information that could guide me. I've scoured the web and can't find what I'm looking for. I need something as small as possible and very directional. My guess is it would have to be something rather high in frequency (GHz?) to get the directionality I desire, like a radio beam or low diameter cone for lack of more technical terms.
To be more specific, I want the transmission to be directional, and the receiver to be able to pick up the signal from any direction (line of sight).
Any information would be greatly appreciated. I haven't committed to attempting this project as I don't have the expertise yet, but I just want to see if it's feasible on a fairly low budget and by someone with just the basics like myself.
