Thats a very broad question. Amd hence the broad answer is yes you could use it for lots of applications. But, i guess you want a specific answer such as this amtenna would be good for application X.
So lets take a look, the peak gain appears to be about 4dBi at around 1.9ghz. For frequencies above that the gain looks pretty poor. If your application was higher frequency than that you could build a better(and smaller antenna). So is the question what is a good application for an 1.9ghz patch antenna?
