WebSep 24, 2013 · It has long been conjectured that isotropic radiation by a simple coherent source is impossible due to changes in polarization. Though hypothetical, the isotropic source is usually taken as the reference for determining a radiator's gain and directivity. Here, we demonstrate both theoretically and experimentally that an isotropic radiator can … WebIn antenna theory, an isotropic radiator is a theoretical, lossless antenna which radiates power uniformly in all directions. The power radiated from the isotropic antenna will have a uniform power per unit area no matter where you measure it from. The isotropic antenna therefore is the reference for all antennas.
