Abstract

Using conventional commercially available computational electromagnetics (CEM) simulation packages the simulation setup for a small antenna array generally is as follows: the complete antenna array structure is modeled in the simulation tool and the simulation is sequentially performed by exciting each single antenna element while all others are terminated with their port reference impedance. This yields a complete characterization of the array in transmit (TX) mode. However, it is a well-known fact that the TX mode characteristics differ from the receive (RX) mode characteristics significantly and the results obtained from a TX mode simulation do not necessarily capture the RX case. In this contribution we first propose an extended model for characterizing RX mode ultra-wideband (UWB) antenna-arrays, with a novel look on the RX mode coupling phenomena. Based on the theory, we propose our computational framework for accurate simulations of small receiving UWB antenna arrays. We further present simulation results for some exemplary UWB antenna arrays and discuss our novel viewpoint on RX mode array coupling.
