Abstract :
The trend towards microcells is likely to result in more base station antennas being sited on the sides of buildings. However, the presence of the wall affects the antenna´s input impedance. This contribution investigates the prediction of this detuning effect using a number of integral equation approaches. The reliability of different approaches is considered and two complex image-based formulations, shown to be especially well suited to this situation, are presented
