Antenna gain is not always negative. There are many cases (Zagi's and microwave dishes for starters) where the antenna gain is positive.

It may depend on the reference used... I mean if your looking at a radiation pattern you could have normalization and then obtain a zero gain... this could be another case... Pay attention also to this things. hope this helps. ciao
