How do I build a small gate for my vegetable patch, made with wire and star droppers?

I have a 3 inch square wire fence around my vegie patch, the posts are star droppers. My dog gets in if I leave to gate open, but the current one, made of the same wire is all bent and broken and difficult to open& close. I need to make something light enough to hand from the star dropper, but it needs to be 1 metre wide by about 1 metre high.
