Hi all,
Does the antenna gain depend on the angle of the emerging ray? or It can be a single number for all ray emerging in all directions?
I know the gain is the amount of power an antenna has relative to an isotropic antenna. Sometimes it means the maximum power an antenna can have relative to the isotropic antenna.
But if it is a directional antenna, each direction would have a different gain. Can we use the maximum gain in equations like:
Pr = Pt Gt Gr / 4 PI r^2 and Effective Area = Gain * Effective Area of an isotropic antenna?
I'm using an antenna of frequency 2.4 GHz
