Antenna Perturbation Modelling And Impact On Radio Channel

In this paper we investigate a joint antenna-channel model, considering stochastic variability on the radiating element. We considered a wide-band monopole antenna with a nearby metallic perturbation, whose position is random. The perturbed antenna characteristics are described through spherical wave expansion modes coefficient distribution in order to produce a stochastic antenna model. This model is then considered in a classical single cluster and indoor industrial channel, in order to evaluate the impact on delay and angular spread.
