Predicting the installed performance of a RF receiver's antenna in its operational environment

This paper presents a modelling technique that predicts the detuning of a RF (Radio Frequency) receiver ahead of its installation into a vehicle. In fact, since the vehicle is rarely available during the equipment's development phase, it becomes necessary to finalise the product even before it can be tested in its operational environment. The proposed model is based on a circuit approach which permits a fast evaluation of the resonant frequency shifting. The comparison with a 3D full wave simulation confirms the robustness of the proposed technique.
