This paper demonstrates a simulation-assisted measurement technique to determine the gain of an antenna accurately in open test site or anechoic chamber. The proposed is based on two-antenna method using Friis equation far-field free-space conditions, with actual setup modelled CST Studio Suite for simulation. An LTE-reject UHF TV log-periodic dipole used validate this paper. simulation order estimate appropriate minimum separation distance between two antennas that needs be for measurements ensure conditions. Determining several simulations instead saves time and effort because it eliminates need perform at various distances. measured realized obtained provides good agreement thus validates accuracy technique.
