In this paper the radiated susceptibility of oscillators is investigated in electromagnetic polluted environment. Oscillator is one the most important constituting block in every RF communication device and its operation dramatically defines the total system performance. The radiated susceptibility of oscillator has been analyzed in term of added phase noise to the intrinsic phase noise of the output spectrum, due to external electromagnetic wave illumination. As a source of threat, the electromagnetic radiation output of WiMax antenna is considered and the output oscillation spectrum is investigated. The method is verified by full wave simulations of a PCB mounting a real oscillator in CST software environment. In addition, analytic verification is done to prove the sensitivity of the oscillator while it has its normal operation.
