Can someone help me about one single p atch antenna gain?
Some one tell me the gain is like dipole only have 2~3 dbi gain.
But I see the manufactuer give me the gain is 6 ~8 dbi.
Why to make the big difference?
I have been doing a lot of microstrip antennas recently. It really depends on the substrate, size, and shape. Radiation efficiency should be in your consideration as well. I saw as high as 8-9 dbi and as low as 1 dbi.
