This one is one from the antennas I use.
I have 4 or 5 of them and finally I have one free to tear apart.
Price was ~ 25 euros before 2 3 years.
They promised me 12 dbi and 120 degrees but diagram is more like 90 100 degrees.
Interesting pattern are found on the pcb board π – it worked for me so there is no mater how it madded .
Here one small antenna witch I have from a long time. I am happy from it – I use it on 5.3ghz band and it works well – it gives what is promised.
Not like omnidirecional trendnet antenna – whitch I do not like
