DIY Patch Antenna - 900mHz - how to?
So I have done a bunch of reading on patch antennas, and they don't seem like very complex beasts. Right now I'm starring at a wikipedia article, and I'm considering going home and cutting some double sided circuit board and plugging it into my rx.
Referencing this article: http://en.wikipedia.org/wiki/Patch_antenna
Is it this simple: Cut the PCB to the dimensions (1/2 wavelength length and width), then solder the front plate to the feed wire and the ground wire to the back side?
In the article it mentioned that the ground plate may need to be slightly larger than the radiator plate (front side). If that is the case I can cut the whole PCB 1/2 inch or an inch too big (length and width), then etch off the copper on the radiator side so that the radiator plate has the 1/2 wavelength dimensions.
If I need to do anything else, please advise...
