Abstract

This paper shows how to predict antenna effects in digital communication system (DCS) software by modelling the antenna as a subsystem. This technique was applied to Vivaldi and commercial dual-band antennas. Initially, a finite impulse response (FIR) model was derived for each S-parameter measurement in an anechoic chamber to derive a system model. This model was then included in DCS software, which enables the estimation of the antenna’s effect in a DCS. Symbol-scattering experiments using an arbitrary waveform generator and an oscilloscope were also performed in an anechoic chamber and then verified using a DCS simulation model. Equivalent noise caused by the radio frequency components was also considered in the simulation. The increase in error vector magnitude (EVM) due to the antennas was found to be similar between the simulations and the experiments. The results also showed that the scattering and EVM changes were dependent on the antenna type employed.
