Radiation Pattern
Power Pattern
Amplitude Field Pattern
Note: The power pattern and the amplitude field pattern are the same when computed and plotted in dB.
Radiation Pattern 2D & 3D Plot
3-D plot ( both θ and vary )
2-D plot ( θ= const plane, vary or = const plane, θ vary )
Some concepts related to the pattern terminology-1
a) 等方向模式（ Isotropic pattern） is the pattern of an antenna having equal radiation in all directions. This is an ideal (not physically achievable) concept. However, it is used to define other antenna parameters. It is represented simply by a sphere whose center coincides with the location of the isotropic radiator. b) 定向天线 （ Directional antenna） is an antenna, which radiates (receives) much more efficiently in som
