Antenna Properties
-
The important properties of an antenna are generally in sonic terms like radiation pattern, radiation.Intensity, polarization gain, directive gain, power gain ,efficiency, effective aperture radiation resistance, beam width, bandwidth etc.For measuring all these types of properties we use Isotropic Radiator that can be defined as a radiator.Pr =Wt/4πr2 watts/m2Wt = total power radiated in wattPr = radial component of average power density poynting vector w/m2r = radius of sphere in meters.
