Claim 0:
1. A method for estimating an antenna gain comprising:
providing an antenna under test having a first phase center, said antenna under test being positioned near an environmental lossy half-space boundary;
providing a probe antenna having a second phase center, said probe antenna being provided at a test distance of the antenna under test near the environmental lossy half-space boundary;
emitting a known electromagnetic signal from the antenna under test;
receiving the emitted known electromagnetic signal at the probe antenna;
measuring an electric field of the received known electromagnetic signal;
calculating a normalized potential at the lossy half-space boundary as a function of distance from the antenna under test; and
estimating the antenna gain for the antenna under test at any distance from the antenna under test using the emitted known electromagnetic signal, the normalized potential, and the measured electric field.
