The presence of non thermal emission detected at radio frequencies in some protostellar jets, constitutes a remarkable discovery with very imporant implications: (1) these low energy systems should be able to accelerate particles up to relativistic energies; (2) when detected, polarized radio emission allow to study magnetic fields with techniques usualy applied to relativistic jets.Here I summarize the main results obtained during my PhD research, devoted to deepen the understanding particle acceleration in protostellar jets, through new JVLA radio observations in wide frequency range These observations allowed to study the jet morphology and the dominant emission nature with unprecedented sensitivity in two representative cases: Te triple source in Serpens, and the HH 80-81 jet.
