A Simple Method for Calculating the Output Voltage at Receive Antenna Terminals Using the Complex Antenna Factor

This letter proposes a simulation model for calculating the output voltage at the terminals of a receiving antenna. By adopting the concept of the complex antenna factor commonly used in the fields of electromagnetic compatibility and electromagnetic interference for its calculation, this model allows one to obtain the received complex voltage signal from the computed scattered fields with the antenna effects fully taken into account. The model is applied to the application of direction-of-arrival estimation.
