I have this 2.4ghz antenna. What way is the antenna supposed to radiate? A OR B?
>>915015
Both I'd imagine.
Looks like a patch antenna. If the metal plate there is the driven element and the PCB is the ground plane, then it's A. If it's the other way around, then B. If I had to guess I'd say B (for the lack of an apparent feed point connecting the coax to the plate), but I'd need to see the other side - ideally in clear enough detail to see traces on the PCB - to say for sure.
cant see traces
wires go to pcb
Anyone?
>>915015
it's a bidirectional antenna

This. Test with laptop or phone, should be pretty obvious.

If the wires go to the PCB, that will be driven element as >>915072 indicated. This most likely means that the metal plate is a reflector, to redirect outputted power. I believe this is the case because the power can freely radiate to the other side.

In that case it's B.

Its lock like is B ( down )
Metal plate is a reflector screen.
but better result you will get with double BiQuad antenna this is 5DB - 9DB in real terms.
